-# GLFW
-
-## Introduction
-
-GLFW is a free, Open Source, multi-platform library for OpenGL and OpenGL ES
-application development.  It provides a simple, platform-independent API for
-creating windows and contexts, reading input, handling events, etc.
-
-Version 3.1 adds improved documentation, support for custom system cursors, file
-drop events, main thread wake-up, window frame size retrieval, floating windows,
-character input with modifier keys, single buffered windows, build improvements
-and fixes for a large number of bugs.
-
-If you are new to GLFW, you may find the
-[introductory tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW
-3 useful.  If you have used GLFW 2 in the past, there is a
-[transition guide](http://www.glfw.org/docs/latest/moving.html) for moving to
-the GLFW 3 API.
-
-Note that a number of source files have been added or renamed in 3.1, which may
-require you to update any custom build files you have.
-
-
-## Compiling GLFW
-
-See the [Compiling GLFW](http://www.glfw.org/docs/latest/compile.html) guide in
-the GLFW documentation.
-
-
-## Using GLFW
-
-See the
-[Building programs that use GLFW](http://www.glfw.org/docs/latest/build.html)
-guide in the GLFW documentation.
-
-
-## Reporting bugs
-
-Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues).
-Please always include the name and version of the OS where the bug occurs and
-the version of GLFW used.  If you have cloned it, include the commit ID used.
-
-If it's a build issue, please also include the build log and the name and
-version of your development environment.
-
-If it's a context creation issue, please also include the make and model of your
-graphics card and the version of your driver.
-
-This will help both us and other people experiencing the same bug.
-
-
-## Dependencies
-
-GLFW bundles a number of dependencies in the `deps/` directory.
-
- - [Khronos extension headers](https://www.opengl.org/registry/) for API
-   extension symbols used by GLFW
- - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples
-   with command-line options
- - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded
-   examples
- - An OpenGL 3.2 core loader generated by
-   [glad](https://github.com/Dav1dde/glad) for examples using modern OpenGL
-
-

-
-@page build Building applications
-
-@tableofcontents
-
-This is about compiling and linking applications that use GLFW.  For information on
-how to write such applications, start with the [introductory tutorial](@ref quick).
-For information on how to compile the GLFW library itself, see the @ref compile
-guide.
-
-This is not a tutorial on compilation or linking.  It assumes basic
-understanding of how to compile and link a C program as well as how to use the
-specific compiler of your chosen development environment.  The compilation
-and linking process should be explained in your C programming material and in
-the documentation for your development environment.
-
-@section build_include Including the GLFW header file
-
-In the source files of your application where you use OpenGL or GLFW, you should
-include the GLFW header file, i.e.:
-
-@code
-#include <GLFW/glfw3.h>
-@endcode
-
-The GLFW header declares the GLFW API and by default also includes the OpenGL
-header of your development environment, which in turn defines all the constants,
-types and function prototypes of the OpenGL API.
-
-The GLFW header also defines everything necessary for your OpenGL header to
-function.  For example, under Windows you are normally required to include
-`windows.h` before the OpenGL header, which would pollute your code namespace
-with the entire Win32 API.
-
-Instead, the GLFW header takes care of this for you, not by including
-`windows.h`, but by duplicating only the very few necessary parts of it.  It
-does this only when needed, so if `windows.h` _is_ included, the GLFW header
-does not try to redefine those symbols.  The reverse is not true, i.e.
-`windows.h` cannot cope if any of its symbols have already been defined.
-
-In other words:
-
- - Do _not_ include the OpenGL headers yourself, as GLFW does this for you
- - Do _not_ include `windows.h` or other platform-specific headers unless you
-   plan on using those APIs directly
- - If you _do_ need to include such headers, do it _before_ including
-   the GLFW header and it will handle this
-
-If you are using an OpenGL extension loading library such as
-[glad](https://github.com/Dav1dde/glad), the extension loader header should
-either be included _before_ the GLFW one, or the `GLFW_INCLUDE_NONE` macro
-(described below) should be defined.
-
-
-@subsection build_macros GLFW header option macros
-
-These macros may be defined before the inclusion of the GLFW header and affect
-its behavior.
-
-`GLFW_DLL` is required on Windows when using the GLFW DLL, to tell the compiler
-that the GLFW functions are defined in a DLL.
-
-The following macros control which OpenGL or OpenGL ES API header is included.
-
-`GLFW_INCLUDE_GLCOREARB` makes the GLFW header include the modern
-`GL/glcorearb.h` header (`OpenGL/gl3.h` on OS X) instead of the regular OpenGL
-header.
-
-`GLFW_INCLUDE_ES1` makes the GLFW header include the OpenGL ES 1.x `GLES/gl.h`
-header instead of the regular OpenGL header.
-
-`GLFW_INCLUDE_ES2` makes the GLFW header include the OpenGL ES 2.0 `GLES2/gl2.h`
-header instead of the regular OpenGL header.
-
-`GLFW_INCLUDE_ES3` makes the GLFW header include the OpenGL ES 3.0 `GLES3/gl3.h`
-header instead of the regular OpenGL header.
-
-`GLFW_INCLUDE_ES31` makes the GLFW header include the OpenGL ES 3.1 `GLES3/gl31.h`
-header instead of the regular OpenGL header.
-
-`GLFW_INCLUDE_NONE` makes the GLFW header not include any OpenGL or OpenGL ES API
-header.  This is useful in combination with an extension loading library.
-
-If none of the above inclusion macros are defined, the standard OpenGL `GL/gl.h`
-header (`OpenGL/gl.h` on OS X) is included.
-
-`GLFW_INCLUDE_GLEXT` makes the GLFW header include the appropriate extension
-header for the OpenGL or OpenGL ES header selected above after and _in addition
-to_ that header.
-
-`GLFW_INCLUDE_GLU` makes the header include the GLU header _in addition to_ the
-header selected above.  This should only be used with the standard OpenGL header
-and only for legacy code.  GLU has been deprecated and should not be used in new
-code.
-
-@note GLFW does not provide any of the API headers mentioned above.  They must
-be provided by your development environment or your OpenGL or OpenGL ES SDK.
-
-
-@section build_link Link with the right libraries
-
-GLFW is essentially a wrapper of various platform-specific APIs and therefore
-needs to link against many different system libraries.  If you are using GLFW as
-a shared library / dynamic library / DLL then it takes care of these links.
-However, if you are using GLFW as a static library then your executable will
-need to link against these libraries.
-
-On Windows and OS X, the list of system libraries is static and can be
-hard-coded into your build environment.  See the section for your development
-environment below.  On Linux and other Unix-like operating systems, the list
-varies but can be retrieved in various ways as described below.
-
-A good general introduction to linking is
-[Beginner's Guide to Linkers](http://www.lurklurk.org/linkers/linkers.html) by
-David Drysdale.
-
-
-@subsection build_link_win32 With MinGW or Visual C++ on Windows
-
-The static version of the GLFW library is named `glfw3`.  When using this
-version, it is also necessary to link with some libraries that GLFW uses.
-
-When linking an application under Windows that uses the static version of GLFW,
-you must link with `opengl32`.  On some versions of MinGW, you must also
-explicitly link with `gdi32`, while other versions of MinGW include it in the
-set of default libraries along with other dependencies like `user32` and
-`kernel32`.  If you are using GLU, you must also link with `glu32`.
-
-The link library for the GLFW DLL is named `glfw3dll`.  When compiling an
-application that uses the DLL version of GLFW, you need to define the `GLFW_DLL`
-macro _before_ any inclusion of the GLFW header.  This can be done either with
-a compiler switch or by defining it in your source code.
-
-An application using the GLFW DLL does not need to link against any of its
-dependencies, but you still have to link against `opengl32` if your application
-uses OpenGL and `glu32` if it uses GLU.
-
-
-@subsection build_link_cmake_source With CMake and GLFW source
-
-With just a few changes to your `CMakeLists.txt` you can have the GLFW source
-tree built along with your application.
-
-Firstly, add the root directory of the GLFW source tree to your project.  This
-will add the `glfw` target and the necessary cache variables to your project.
-
-@code{.cmake}
-add_subdirectory(path/to/glfw)
-@endcode
-
-To be able to include the GLFW header from your code, you need to tell the
-compiler where to find it.
-
-@code{.cmake}
-include_directories(path/to/glfw/include)
-@endcode
-
-Once GLFW has been added to the project, the `GLFW_LIBRARIES` cache variable
-contains all link-time dependencies of GLFW as it is currently configured.  To
-link against GLFW, link against them and the `glfw` target.
-
-@code{.cmake}
-target_link_libraries(myapp glfw ${GLFW_LIBRARIES})
-@endcode
-
-Note that `GLFW_LIBRARIES` does not include GLU, as GLFW does not use it.  If
-your application needs GLU, you can add it to the list of dependencies with the
-`OPENGL_glu_LIBRARY` cache variable, which is implicitly created when the GLFW
-CMake files look for OpenGL.
-
-@code{.cmake}
-target_link_libraries(myapp glfw ${OPENGL_glu_LIBRARY} ${GLFW_LIBRARIES})
-@endcode
-
-
-@subsection build_link_cmake_pkgconfig With CMake on Unix and installed GLFW binaries
-
-CMake can import settings from pkg-config, which GLFW supports.  When you
-installed GLFW, the pkg-config file `glfw3.pc` was installed along with it.
-
-First you need to find the PkgConfig package.  If this fails, you may need to
-install the pkg-config package for your distribution.
-
-@code{.cmake}
-find_package(PkgConfig REQUIRED)
-@endcode
-
-This creates the CMake commands to find pkg-config packages.  Then you need to
-find the GLFW package.
-
-@code{.cmake}
-pkg_search_module(GLFW REQUIRED glfw3)
-@endcode
-
-This creates the CMake variables you need to use GLFW.  To be able to include
-the GLFW header, you need to tell your compiler where it is.
-
-@code{.cmake}
-include_directories(${GLFW_INCLUDE_DIRS})
-@endcode
-
-You also need to link against the correct libraries.  If you are using the
-shared library version of GLFW, use the `GLFW_LIBRARIES` variable.
-
-@code{.cmake}
-target_link_libraries(simple ${GLFW_LIBRARIES})
-@endcode
-
-If you are using the static library version of GLFW, use the
-`GLFW_STATIC_LIBRARIES` variable instead.
-
-@code{.cmake}
-target_link_libraries(simple ${GLFW_STATIC_LIBRARIES})
-@endcode
-
-
-@subsection build_link_pkgconfig With pkg-config on OS X or other Unix
-
-GLFW supports [pkg-config](http://www.freedesktop.org/wiki/Software/pkg-config/),
-and the `glfw3.pc` pkf-config file is generated when the GLFW library is built
-and is installed along with it.  A pkg-config file describes all necessary
-compile-time and link-time flags and dependencies needed to use a library.  When
-they are updated or if they differ between systems, you will get the correct
-ones automatically.
-
-A typical compile and link command-line when using the static version of the
-GLFW library may look like this:
-
-@code{.sh}
-cc `pkg-config --cflags glfw3` -o myprog myprog.c `pkg-config --static --libs glfw3`
-@endcode
-
-If you are using the shared version of the GLFW library, simply omit the
-`--static` flag.
-
-@code{.sh}
-cc `pkg-config --cflags glfw3` -o myprog myprog.c `pkg-config --libs glfw3`
-@endcode
-
-You can also use the `glfw3.pc` file without installing it first, by using the
-`PKG_CONFIG_PATH` environment variable.
-
-@code{.sh}
-env PKG_CONFIG_PATH=path/to/glfw/src cc `pkg-config --cflags glfw3` -o myprog myprog.c `pkg-config --libs glfw3`
-@endcode
-
-The dependencies do not include GLU, as GLFW does not need it.  On OS X, GLU is
-built into the OpenGL framework, so if you need GLU you don't need to do
-anything extra.  If you need GLU and are using Linux or BSD, you should add the
-`glu` pkg-config module.
-
-@code{.sh}
-cc `pkg-config --cflags glfw3 glu` -o myprog myprog.c `pkg-config --libs glfw3 glu`
-@endcode
-
-If you are using the static version of the GLFW library, make sure you don't link statically against GLU.
-
-@code{.sh}
-cc `pkg-config --cflags glfw3 glu` -o myprog myprog.c `pkg-config --static --libs glfw3` `pkg-config --libs glu`
-@endcode
-
-
-@subsection build_link_xcode With Xcode on OS X
-
-If you are using the dynamic library version of GLFW, simply add it to the
-project dependencies.
-
-If you are using the static library version of GLFW, add it and the Cocoa,
-OpenGL, IOKit, CoreVideo and Carbon frameworks to the project as dependencies.
-They can all be found in `/System/Library/Frameworks`.
-
-@note GLFW needs the Carbon framework only to access the current keyboard layout
-via the Text Input Source Services.  This is one of the non-deprecated parts of
-the Carbon API and the only way to access this information on OS X.
-
-
-@subsection build_link_osx With command-line on OS X
-
-It is recommended that you use [pkg-config](@ref build_link_pkgconfig) when
-building from the command line on OS X.  That way you will get any new
-dependencies added automatically.  If you still wish to build manually, you need
-to add the required frameworks and libraries to your command-line yourself using
-the `-l` and `-framework` switches.
-
-If you are using the dynamic GLFW library, which is named `libglfw.3.dylib`, do:
-
-@code{.sh}
-cc -o myprog myprog.c -lglfw -framework Cocoa -framework OpenGL -framework IOKit -framework CoreVideo
-@endcode
-
-If you are using the static library, named `libglfw3.a`, substitute `-lglfw3`
-for `-lglfw`.
-
-Note that you do not add the `.framework` extension to a framework when linking
-against it from the command-line.
-
-The OpenGL framework contains both the OpenGL and GLU APIs, so there is nothing
-special to do when using GLU.  Also note that even though your machine may have
-`libGL`-style OpenGL libraries, they are for use with the X Window System and
-will _not_ work with the OS X native version of GLFW.

-
-@tableofcontents
-
-This guide describes the various API extensions used by this version of GLFW.
-It lists what are essentially implementation details, but which are nonetheless
-vital knowledge for developers intending to deploy their applications on a wide
-range of machines.
-
-The information in this guide is not a part of GLFW API, but merely
-preconditions for some parts of the library to function on a given machine.  Any
-part of this information may change in future versions of GLFW and that will not
-be considered a breaking API change.
-
-
-@section compat_x11 X11 extensions, protocols and IPC standards
-
-As GLFW uses Xlib directly, without any intervening toolkit
-library, it has sole responsibility for interacting well with the many and
-varied window managers in use on Unix-like systems.  In order for applications
-and window managers to work well together, a number of standards and
-conventions have been developed that regulate behavior outside the scope of the
-X11 API; most importantly the
-[Inter-Client Communication Conventions Manual](http://www.tronche.com/gui/x/icccm/)
-(ICCCM) and
-[Extended Window Manager Hints](http://standards.freedesktop.org/wm-spec/wm-spec-latest.html)
-(EWMH) standards.
-
-GLFW uses the `_MOTIF_WM_HINTS` window property to support borderless windows.
-If the running window manager does not support this property, the
-`GLFW_DECORATED` hint will have no effect.
-
-GLFW uses the ICCCM `WM_DELETE_WINDOW` protocol to intercept the user
-attempting to close the GLFW window.  If the running window manager does not
-support this protocol, the close callback will never be called.
-
-GLFW uses the EWMH `_NET_WM_PING` protocol, allowing the window manager notify
-the user when the application has stopped responding, i.e. when it has ceased to
-process events.  If the running window manager does not support this protocol,
-the user will not be notified if the application locks up.
-
-GLFW uses the EWMH `_NET_WM_STATE_FULLSCREEN` window state to tell the window
-manager to make the GLFW window full screen.  If the running window manager does
-not support this state, full screen windows may not work properly.  GLFW has
-a fallback code path in case this state is unavailable, but every window manager
-behaves slightly differently in this regard.
-
-GLFW uses the EWMH `_NET_WM_BYPASS_COMPOSITOR` window property to tell a
-compositing window manager to un-redirect full screen GLFW windows.  If the
-running window manager uses compositing but does not support this property then
-additional copying may be performed for each buffer swap of full screen windows.
-
-GLFW uses the
-[clipboard manager protocol](http://www.freedesktop.org/wiki/ClipboardManager/)
-to push a clipboard string (i.e. selection) owned by a GLFW window about to be
-destroyed to the clipboard manager.  If there is no running clipboard manager,
-the clipboard string will be unavailable once the window has been destroyed.
-
-GLFW uses the
-[X drag-and-drop protocol](http://www.freedesktop.org/wiki/Specifications/XDND/)
-to provide file drop events.  If the application originating the drag does not
-support this protocol, drag and drop will not work.
-
-GLFW uses the XInput 2 extension to provide sub-pixel cursor motion events.  If
-the running X server does not support this version of this extension, cursor
-motion will be snapped to the pixel grid.
-
-GLFW uses the XRandR 1.3 extension to provide multi-monitor support.  If the
-running X server does not support this version of this extension, multi-monitor
-support will not function and only a single, desktop-spanning monitor will be
-reported.
-
-GLFW uses the XRandR 1.3 and Xf86vidmode extensions to provide gamma ramp
-support.  If the running X server does not support either or both of these
-extensions, gamma ramp support will not function.
-
-GLFW uses the Xkb extension and detectable auto-repeat to provide keyboard
-input.  If the running X server does not support this extension, a non-Xkb
-fallback path is used.
-
-
-@section compat_glx GLX extensions
-
-The GLX API is the default API used to create OpenGL contexts on Unix-like
-systems using the X Window System.
-
-GLFW uses the GLX 1.3 `GLXFBConfig` functions to enumerate and select framebuffer pixel
-formats.  If GLX 1.3 is not supported, @ref glfwInit will fail.
-
-GLFW uses the `GLX_MESA_swap_control,` `GLX_EXT_swap_control` and
-`GLX_SGI_swap_control` extensions to provide vertical retrace synchronization
-(or _vsync_), in that order of preference.  Where none of these extension are
-available, calling @ref glfwSwapInterval will have no effect.
-
-GLFW uses the `GLX_ARB_multisample` extension to create contexts with
-multisampling anti-aliasing.  Where this extension is unavailable, the
-`GLFW_SAMPLES` hint will have no effect.
-
-GLFW uses the `GLX_ARB_create_context` extension when available, even when
-creating OpenGL contexts of version 2.1 and below.  Where this extension is
-unavailable, the `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR`
-hints will only be partially supported, the `GLFW_OPENGL_DEBUG_CONTEXT` hint
-will have no effect, and setting the `GLFW_OPENGL_PROFILE` or
-`GLFW_OPENGL_FORWARD_COMPAT` hints to `GL_TRUE` will cause @ref
-glfwCreateWindow to fail.
-
-GLFW uses the `GLX_ARB_create_context_profile` extension to provide support for
-context profiles.  Where this extension is unavailable, setting the
-`GLFW_OPENGL_PROFILE` hint to anything but `GLFW_OPENGL_ANY_PROFILE`, or setting
-`GLFW_CLIENT_API` to anything but `GLFW_OPENGL_API` will cause @ref
-glfwCreateWindow to fail.
-
-GLFW uses the `GLX_ARB_context_flush_control` extension to provide control over
-whether a context is flushed when it is released (made non-current).  Where this
-extension is unavailable, the `GLFW_CONTEXT_RELEASE_BEHAVIOR` hint will have no
-effect and the context will always be flushed when released.
-
-@section compat_wgl WGL extensions
-
-The WGL API is used to create OpenGL contexts on Microsoft Windows and other
-implementations of the Win32 API, such as Wine.
-
-GLFW uses either the `WGL_EXT_extension_string` or the
-`WGL_ARB_extension_string` extension to check for the presence of all other WGL
-extensions listed below.  If both are available, the EXT one is preferred.  If
-neither is available, no other extensions are used and many GLFW features
-related to context creation will have no effect or cause errors when used.
-
-GLFW uses the `WGL_EXT_swap_control` extension to provide vertical retrace
-synchronization (or _vsync_).  Where this extension is unavailable, calling @ref
-glfwSwapInterval will have no effect.
-
-GLFW uses the `WGL_ARB_pixel_format` and `WGL_ARB_multisample` extensions to
-create contexts with multisampling anti-aliasing.  Where these extensions are
-unavailable, the `GLFW_SAMPLES` hint will have no effect.
-
-GLFW uses the `WGL_ARB_create_context` extension when available, even when
-creating OpenGL contexts of version 2.1 and below.  Where this extension is
-unavailable, the `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR`
-hints will only be partially supported, the `GLFW_OPENGL_DEBUG_CONTEXT` hint
-will have no effect, and setting the `GLFW_OPENGL_PROFILE` or
-`GLFW_OPENGL_FORWARD_COMPAT` hints to `GL_TRUE` will cause @ref
-glfwCreateWindow to fail.
-
-GLFW uses the `WGL_ARB_create_context_profile` extension to provide support for
-context profiles.  Where this extension is unavailable, setting the
-`GLFW_OPENGL_PROFILE` hint to anything but `GLFW_OPENGL_ANY_PROFILE` will cause
-@ref glfwCreateWindow to fail.
-
-GLFW uses the `WGL_ARB_context_flush_control` extension to provide control over
-whether a context is flushed when it is released (made non-current).  Where this
-extension is unavailable, the `GLFW_CONTEXT_RELEASE_BEHAVIOR` hint will have no
-effect and the context will always be flushed when released.
-
-@section compat_osx OpenGL 3.2 and later on OS X
-
-Support for OpenGL 3.2 and above was introduced with OS X 10.7 and even then
-only forward-compatible, core profile contexts are supported.  Support for
-OpenGL 4.1 was introduced with OS X 10.9, also limited to forward-compatible,
-core profile contexts.  There is also still no mechanism for requesting debug
-contexts.  Versions of Mac OS X earlier than 10.7 support at most OpenGL
-version 2.1.
-
-Because of this, on OS X 10.7 and later, the `GLFW_CONTEXT_VERSION_MAJOR` and
-`GLFW_CONTEXT_VERSION_MINOR` hints will cause @ref glfwCreateWindow to fail if
-given version 3.0 or 3.1, the `GLFW_OPENGL_FORWARD_COMPAT` hint must be set to
-`GL_TRUE` and the `GLFW_OPENGL_PROFILE` hint must be set to
-`GLFW_OPENGL_CORE_PROFILE` when creating OpenGL 3.2 and later contexts and the
-`GLFW_OPENGL_DEBUG_CONTEXT` hint is ignored.
-
-Also, on Mac OS X 10.6 and below, the `GLFW_CONTEXT_VERSION_MAJOR` and
-`GLFW_CONTEXT_VERSION_MINOR` hints will fail if given a version above 2.1,
-setting the `GLFW_OPENGL_PROFILE` or `GLFW_OPENGL_FORWARD_COMPAT` hints to
-a non-default value will cause @ref glfwCreateWindow to fail and the
-`GLFW_OPENGL_DEBUG_CONTEXT` hint is ignored.

-
-
-@section compile_cmake Using CMake
-
-GLFW uses [CMake](http://www.cmake.org/) to generate project files or makefiles
-for a particular development environment.  If you are on a Unix-like system such
-as Linux or FreeBSD or have a package system like Fink, MacPorts, Cygwin or
-Homebrew, you can simply install its CMake package.  If not, you can download
-installers for Windows and OS X from the [CMake website](http://www.cmake.org/).
-
-@note CMake only generates project files or makefiles.  It does not compile the
-actual GLFW library.  To compile GLFW, first generate these files and then use
-them in your chosen development environment to compile the actual GLFW library.
-
-
-@subsection compile_deps Dependencies
-
-Once you have installed CMake, make sure that all other dependencies are
-available.  On some platforms, GLFW needs a few additional packages to be
-installed.  See the section for your chosen platform and development environment
-below.
-
-
-@subsubsection compile_deps_msvc Dependencies for Visual C++ on Windows
-
-The Microsoft Platform SDK that is installed along with Visual C++ already
-contains all the necessary headers, link libraries and tools except for CMake.
-Move on to @ref compile_generate.
-
-
-@subsubsection compile_deps_mingw Dependencies for MinGW or MinGW-w64 on Windows
-
-Both the MinGW and the MinGW-w64 packages already contain all the necessary
-headers, link libraries and tools except for CMake.  Move on to @ref
-compile_generate.
-
-
-@subsubsection compile_deps_mingw_cross Dependencies for MinGW or MinGW-w64 cross-compilation
-
-Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages.  For
-example, Cygwin has the `mingw64-i686-gcc` and `mingw64-x86_64-gcc` packages
-for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives
-like Ubuntu have the `mingw-w64` package for both.
-
-GLFW has CMake toolchain files in the `CMake/` directory that allow for easy
-cross-compilation of Windows binaries.  To use these files you need to add a
-special parameter when generating the project files or makefiles:
-
-@code{.sh}
-cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> .
-@endcode
-
-The exact toolchain file to use depends on the prefix used by the MinGW or
-MinGW-w64 binaries on your system.  You can usually see this in the /usr
-directory.  For example, both the Debian/Ubuntu and Cygwin MinGW-w64 packages
-have `/usr/x86_64-w64-mingw32` for the 64-bit compilers, so the correct
-invocation would be:
-
-@code{.sh}
-cmake -DCMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake .
-@endcode
-
-For more details see the article
-[CMake Cross Compiling](http://www.paraview.org/Wiki/CMake_Cross_Compiling) on
-the CMake wiki.
-
-Once you have this set up, move on to @ref compile_generate.
-
-
-@subsubsection compile_deps_xcode Dependencies for Xcode on OS X
-
-Xcode comes with all necessary tools except for CMake.  The required headers
-and libraries are included in the core OS X frameworks.  Xcode can be downloaded
-from the Mac App Store or from the ADC Member Center.
-
-Once you have Xcode installed, move on to @ref compile_generate.
-
-
-@subsubsection compile_deps_x11 Dependencies for Linux and X11
-
-To compile GLFW for X11, you need to have the X11 and OpenGL header packages
-installed, as well as the basic development tools like GCC and make.  For
-example, on Ubuntu and other distributions based on Debian GNU/Linux, you need
-to install the `xorg-dev` and `libglu1-mesa-dev` packages.  The former pulls in
-all X.org header packages and the latter pulls in the Mesa OpenGL and GLU
-packages.  GLFW itself doesn't need or use GLU, but some of the examples do.
-Note that using header files and libraries from Mesa during compilation
-_will not_ tie your binaries to the Mesa implementation of OpenGL.
-
-Once you have installed the necessary packages, move on to @ref
-compile_generate.
-
-
-@subsection compile_generate Generating build files with CMake
-
-Once you have all necessary dependencies it is time to generate the project
-files or makefiles for your development environment.  CMake needs to know two
-paths for this: the path to the _root_ directory of the GLFW source tree (i.e.
-_not_ the `src` subdirectory) and the target path for the generated files and
-compiled binaries.  If these are the same, it is called an in-tree build,
-otherwise it is called an out-of-tree build.
-
-One of several advantages of out-of-tree builds is that you can generate files
-and compile for different development environments using a single source tree.
-
-@note This section is about generating the project files or makefiles necessary
-to compile the GLFW library, not about compiling the actual library.
-
-
-@subsubsection compile_generate_cli Generating files with the CMake command-line tool
-
-To make an in-tree build, enter the _root_ directory of the GLFW source tree
-(i.e. _not_ the `src` subdirectory) and run CMake.  The current directory is
-used as target path, while the path provided as an argument is used to find the
-source tree.
-
-@code{.sh}
-cd <glfw-root-dir>
-cmake .
-@endcode
-
-To make an out-of-tree build, make another directory, enter it and run CMake
-with the (relative or absolute) path to the root of the source tree as an
-argument.
-
-@code{.sh}
-cd <glfw-root-dir>
-mkdir build
-cd build
-cmake ..
-@endcode
-
-Once you have generated the project files or makefiles for your chosen
-development environment, move on to @ref compile_compile.
-
-
-@subsubsection compile_generate_gui Generating files with the CMake GUI
-
-If you are using the GUI version, choose the root of the GLFW source tree as
-source location and the same directory or another, empty directory as the
-destination for binaries.  Choose _Configure_, change any options you wish to,
-_Configure_ again to let the changes take effect and then _Generate_.
-
-Once you have generated the project files or makefiles for your chosen
-development environment, move on to @ref compile_compile.
-
-
-@subsection compile_compile Compiling the library
-
-You should now have all required dependencies and the project files or makefiles
-necessary to compile GLFW.  Go ahead and compile the actual GLFW library with
-these files, as you would with any other project.
-
-Once the GLFW library is compiled, you are ready to build your applications,
-linking it to the GLFW library.  See the @ref build guide for more information.
-
-
-@subsection compile_options CMake options
-
-The CMake files for GLFW provide a number of options, although not all are
-available on all supported platforms.  Some of these are de facto standards
-among projects using CMake and so have no `GLFW_` prefix.
-
-If you are using the GUI version of CMake, these are listed and can be changed
-from there.  If you are using the command-line version, use the `ccmake` tool.
-Some package systems like Ubuntu and other distributions based on Debian
-GNU/Linux have this tool in a separate `cmake-curses-gui` package.
-
-
-@subsubsection compile_options_shared Shared CMake options
-
-`BUILD_SHARED_LIBS` determines whether GLFW is built as a static
-library or as a DLL / shared library / dynamic library.
-
-`LIB_SUFFIX` affects where the GLFW shared /dynamic library is installed.  If it
-is empty, it is installed to `${CMAKE_INSTALL_PREFIX}/lib`.  If it is set to
-`64`, it is installed to `${CMAKE_INSTALL_PREFIX}/lib64`.
-
-`GLFW_CLIENT_LIBRARY` determines which client API library to use.  If set to
-`opengl` the OpenGL library is used, if set to `glesv1` for the OpenGL ES 1.x
-library is used, or if set to `glesv2` the OpenGL ES 2.0 library is used.  The
-selected library and its header files must be present on the system for this to
-work.
-
-`GLFW_BUILD_EXAMPLES` determines whether the GLFW examples are built
-along with the library.
-
-`GLFW_BUILD_TESTS` determines whether the GLFW test programs are
-built along with the library.
-
-`GLFW_BUILD_DOCS` determines whether the GLFW documentation is built along with
-the library.
-
-
-@subsubsection compile_options_osx OS X specific CMake options
-
-`GLFW_USE_CHDIR` determines whether `glfwInit` changes the current
-directory of bundled applications to the `Contents/Resources` directory.
-
-`GLFW_USE_MENUBAR` determines whether the first call to
-`glfwCreateWindow` sets up a minimal menu bar.
-
-`GLFW_USE_RETINA` determines whether windows will use the full resolution of
-Retina displays.
-
-`GLFW_BUILD_UNIVERSAL` determines whether to build Universal Binaries.
-
-
-@subsubsection compile_options_win32 Windows specific CMake options
-
-`USE_MSVC_RUNTIME_LIBRARY_DLL` determines whether to use the DLL version or the
-static library version of the Visual C++ runtime library.  If set to `ON`, the
-DLL version of the Visual C++ library is used.  It is recommended to set this to
-`ON`, as this keeps the executable smaller and benefits from security and bug
-fix updates of the Visual C++ runtime.
-
-`GLFW_USE_DWM_SWAP_INTERVAL` determines whether the swap interval is set even
-when DWM compositing is enabled.  If this is `ON`, the swap interval is set even
-if DWM is enabled.  It is recommended to set this to `OFF`, as doing otherwise
-can lead to severe jitter.
-
-`GLFW_USE_OPTIMUS_HPG` determines whether to export the `NvOptimusEnablement`
-symbol, which forces the use of the high-performance GPU on Nvidia Optimus
-systems.  This symbol needs to be exported by the EXE to be detected by the
-driver, so the override will not work if GLFW is built as a DLL.  See _Enabling
-High Performance Graphics Rendering on Optimus Systems_ for more details.
-
-
-@subsubsection compile_options_egl EGL specific CMake options
-
-`GLFW_USE_EGL` determines whether to use EGL instead of the platform-specific
-context creation API.  Note that EGL is not yet provided on all supported
-platforms.
-
-
-@section compile_manual Compiling GLFW manually
-
-If you wish to compile GLFW without its CMake build environment then you will
-have to do at least some of the platform detection yourself.  GLFW needs
-a number of configuration macros to be defined in order to know what it's being
-compiled for and has many optional, platform-specific ones for various features.
-
-When building with CMake, the `glfw_config.h` configuration header is generated
-based on the current platform and CMake options.  The GLFW CMake environment
-defines `_GLFW_USE_CONFIG_H`, which causes this header to be included by
-`internal.h`.  Without this macro, GLFW will expect the necessary configuration
-macros to be defined on the command-line.
-
-Three macros _must_ be defined when compiling GLFW: one selecting the window
-creation API, one selecting the context creation API and one client library.
-Exactly one of each kind must be defined for GLFW to compile and link.
-
-The window creation API is used to create windows, handle input, monitors, gamma
-ramps and clipboard.  The options are:
-
- - `_GLFW_COCOA` to use the Cocoa frameworks
- - `_GLFW_WIN32` to use the Win32 API
- - `_GLFW_X11` to use the X Window System
- - `_GLFW_WAYLAND` to use the Wayland API (experimental and incomplete)
- - `_GLFW_MIR` to use the Mir API (experimental and incomplete)
-
-The context creation API is used to enumerate pixel formats / framebuffer
-configurations and to create contexts.  The options are:
-
- - `_GLFW_NSGL` to use the Cocoa OpenGL framework
- - `_GLFW_WGL` to use the Win32 WGL API
- - `_GLFW_GLX` to use the X11 GLX API
- - `_GLFW_EGL` to use the EGL API
-
-Wayland and Mir both require the EGL backend.
-
-The client library is the one providing the OpenGL or OpenGL ES API, which is
-used by GLFW to probe the created context.  This is not the same thing as the
-client API, as many desktop OpenGL client libraries now expose the OpenGL ES API
-through extensions.  The options are:
-
- - `_GLFW_USE_OPENGL` for the desktop OpenGL (opengl32.dll, libGL.so or
-   OpenGL.framework)
- - `_GLFW_USE_GLESV1` for OpenGL ES 1.x (experimental)
- - `_GLFW_USE_GLESV2` for OpenGL ES 2.x (experimental)
-
-Note that `_GLFW_USE_GLESV1` and `_GLFW_USE_GLESV2` may only be used with EGL,
-as the other context creation APIs do not interface with OpenGL ES client
-libraries.
-
-If you are building GLFW as a shared library / dynamic library / DLL then you
-must also define `_GLFW_BUILD_DLL`.  Otherwise, you may not define it.
-
-If you are using the X11 window creation API then you _must_ also select an entry
-point retrieval mechanism.
-
- - `_GLFW_HAS_GLXGETPROCADDRESS` to use `glXGetProcAddress` (recommended)
- - `_GLFW_HAS_GLXGETPROCADDRESSARB` to use `glXGetProcAddressARB` (legacy)
- - `_GLFW_HAS_GLXGETPROCADDRESSEXT` to use `glXGetProcAddressEXT` (legacy)
- - `_GLFW_HAS_DLOPEN` to do manual retrieval with `dlopen` (fallback)
-
-If you are using the Cocoa window creation API, the following options are
-available:
-
- - `_GLFW_USE_CHDIR` to `chdir` to the `Resources` subdirectory of the
-   application bundle during @ref glfwInit (recommended)
- - `_GLFW_USE_MENUBAR` to create and populate the menu bar when the first window
-   is created (recommended)
- - `_GLFW_USE_RETINA` to have windows use the full resolution of Retina displays
-   (recommended)

-
-@page context Context guide
-
-@tableofcontents
-
-This guide introduces the OpenGL and OpenGL ES context related functions of
-GLFW.  There are also guides for the other areas of the GLFW API.
-
- - @ref intro
- - @ref window
- - @ref monitor
- - @ref input
-
-
-@section context_object Context objects
-
-A window object encapsulates both a top-level window and an OpenGL or OpenGL ES
-context.  It is created with @ref glfwCreateWindow and destroyed with @ref
-glfwDestroyWindow or @ref glfwTerminate.  See @ref window_creation for more
-information.
-
-As the window and context are inseparably linked, the window object also serves
-as the context handle.
-
-To test the creation of various kinds of contexts and see their properties, run
-the `glfwinfo` test program.
-
-
-@subsection context_hints Context creation hints
-
-There are a number of hints, specified using @ref glfwWindowHint, related to
-what kind of context is created.  See
-[context related hints](@ref window_hints_ctx) in the window guide.
-
-
-@subsection context_sharing Context object sharing
-
-When creating a window and its OpenGL or OpenGL ES context with @ref
-glfwCreateWindow, you can specify another window whose context the new one
-should share its objects (textures, vertex and element buffers, etc.) with.
-
-@code
-GLFWwindow* second_window = glfwCreateWindow(640, 480, "Second Window", NULL, first_window);
-@endcode
-
-Object sharing is implemented by the operating system and graphics driver.  On
-platforms where it is possible to choose which types of objects are shared, GLFW
-requests that all types are shared.
-
-See the relevant chapter of the [OpenGL](https://www.opengl.org/registry/) or
-[OpenGL ES](http://www.khronos.org/opengles/) reference documents for more
-information.  The name and number of this chapter unfortunately varies between
-versions and APIs, but has at times been named _Shared Objects and Multiple
-Contexts_.
-
-GLFW comes with a simple object sharing test program called `sharing`.
-
-
-@subsection context_offscreen Offscreen contexts
-
-GLFW doesn't support creating contexts without an associated window.  However,
-contexts with hidden windows can be created with the
-[GLFW_VISIBLE](@ref window_hints_wnd) window hint.
-
-@code
-glfwWindowHint(GLFW_VISIBLE, GL_FALSE);
-
-GLFWwindow* offscreen_context = glfwCreateWindow(640, 480, "", NULL, NULL);
-@endcode
-
-The window never needs to be shown and its context can be used as a plain
-offscreen context.  Depending on the window manager, the size of a hidden
-window's framebuffer may not be usable or modifiable, so framebuffer
-objects are recommended for rendering with such contexts.
-
-__OS X:__ The first time a window is created the menu bar is populated with
-common commands like Hide, Quit and About.  This is not desirable for example
-when writing a command-line only application.  The menu bar setup can be
-disabled with a [compile-time option](@ref compile_options_osx).
-
-
-@section context_current Current context
-
-Before you can make OpenGL or OpenGL ES calls, you need to have a current
-context of the correct type.  A context can only be current for a single thread
-at a time, and a thread can only have a single context current at a time.
-
-The context of a window is made current with @ref glfwMakeContextCurrent.
-
-@code
-glfwMakeContextCurrent(window);
-@endcode
-
-The window of the current context is returned by @ref glfwGetCurrentContext.
-
-@code
-GLFWwindow* window = glfwGetCurrentContext();
-@endcode
-
-The following GLFW functions require a context to be current.  Calling any these
-functions without a current context will generate a @ref GLFW_NO_CURRENT_CONTEXT
-error.
-
- - @ref glfwSwapInterval
- - @ref glfwExtensionSupported
- - @ref glfwGetProcAddress
-
-
-@section context_swap Buffer swapping
-
-Buffer swapping is part of the window and framebuffer, not the context.  See
-@ref buffer_swap.
-
-
-@section context_glext OpenGL and OpenGL ES extensions
-
-One of the benefits of OpenGL and OpenGL ES are their extensibility.
-Hardware vendors may include extensions in their implementations that extend the
-API before that functionality is included in a new version of the OpenGL or
-OpenGL ES specification, and some extensions are never included and remain
-as extensions until they become obsolete.
-
-An extension is defined by:
-
-- An extension name (e.g. `GL_ARB_debug_output`)
-- New OpenGL tokens (e.g. `GL_DEBUG_SEVERITY_HIGH_ARB`)
-- New OpenGL functions (e.g. `glGetDebugMessageLogARB`)
-
-Note the `ARB` affix, which stands for Architecture Review Board and is used
-for official extensions.  The extension above was created by the ARB, but there
-are many different affixes, like `NV` for Nvidia and `AMD` for, well, AMD.  Any
-group may also use the generic `EXT` affix.  Lists of extensions, together with
-their specifications, can be found at the
-[OpenGL Registry](http://www.opengl.org/registry/) and
-[OpenGL ES Registry](https://www.khronos.org/registry/gles/).
-
-
-@subsection context_glext_auto Loading extension with a loader library
-
-An extension loader library is the easiest and best way to access both OpenGL and
-OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs.
-They will take care of all the details of declaring and loading everything you
-need.  One such library is [glad](https://github.com/Dav1dde/glad) and there are
-several others.  
-
-The following example will use glad but all extension loader libraries work
-similarly.
-
-First you need to generate the source files using the glad Python script.  This
-example generates a loader for any version of OpenGL, which is the default for
-both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific
-API versions and extension sets can be generated.  The generated files are
-written to the `output` directory.
-
-@code{.sh}
-python main.py --generator c --no-loader --out-path output
-@endcode
-
-The `--no-loader` option is added because GLFW already provides a function for
-loading OpenGL and OpenGL ES function pointers and glad can call this instead of
-having to implement its own.  There are several other command-line options as
-well.  See the glad documentation for details.
-
-Add the generated `output/src/glad.c`, `output/include/glad/glad.h` and
-`output/include/KHR/khrplatform.h` files to your build.  Then you need to
-include the glad header file, which will replace the OpenGL header of your
-development environment.  By including the glad header before the GLFW header,
-it suppresses the development environment's OpenGL or OpenGL ES header.
-
-@code
-#include <glad/glad.h>
-#include <GLFW/glfw3.h>
-@endcode
-
-Finally you need to initialize glad once you have a suitable current context.
-
-@code
-window = glfwCreateWindow(640, 480, "My Window", NULL, NULL);
-if (!window)
-{
-    ...
-}
-
-glfwMakeContextCurrent(window);
-
-gladLoadGLLoader((GLADloadproc) glfwGetProcAddress);
-@endcode
-
-Once glad has been loaded, you have access to all OpenGL core and extension
-functions supported by both the context you created and the glad loader you
-generated and you are ready to start rendering.
-
-You can specify a minimum required OpenGL or OpenGL ES version with
-[context hints](@ref window_hints_ctx).  If your needs are more complex, you can
-check the actual OpenGL or OpenGL ES version with
-[context attributes](@ref window_attribs_ctx), or you can check whether
-a specific version is supported by the current context with the
-`GLAD_GL_VERSION_x_x` booleans.
-
-@code
-if (GLAD_GL_VERSION_3_2)
-{
-    // Call OpenGL 3.2+ specific code
-}
-@endcode
-
-To check whether a specific extension is supported, use the `GLAD_GL_xxx`
-booleans.
-
-@code
-if (GLAD_GL_ARB_debug_output)
-{
-    // Use GL_ARB_debug_output
-}
-@endcode
-
-
-@subsection context_glext_manual Loading extensions manually
-
-__Do not use this technique__ unless it is absolutely necessary.  An
-[extension loader library](@ref context_glext_auto) will save you a ton of
-tedious, repetitive, error prone work.
-
-To use a certain extension, you must first check whether the context supports
-that extension and then, if it introduces new functions, retrieve the pointers
-to those functions.  GLFW provides @ref glfwExtensionSupported and @ref
-glfwGetProcAddress for manual loading of extensions and new API functions.
-
-This section will demonstrate manual loading of OpenGL extensions.  The loading
-of OpenGL ES extensions is identical except for the name of the extension header.
-
-
-@subsubsection context_glext_header The glext.h header
-
-The `glext.h` extension header is a continually updated file that defines the
-interfaces for all OpenGL extensions.  The latest version of this can always be
-found at the [OpenGL Registry](http://www.opengl.org/registry/).  There are also
-extension headers for the various versions of OpenGL ES at the
-[OpenGL ES Registry](https://www.khronos.org/registry/gles/).  It it strongly
-recommended that you use your own copy of the extension header, as the one
-included in your development environment may be several years out of date and
-may not include the extensions you wish to use.
-
-The header defines function pointer types for all functions of all extensions it
-supports.  These have names like `PFNGLGETDEBUGMESSAGELOGARBPROC` (for
-`glGetDebugMessageLogARB`), i.e. the name is made uppercase and `PFN` (pointer
-to function) and `PROC` (procedure) are added to the ends.
-
-To include the extension header, define [GLFW_INCLUDE_GLEXT](@ref build_macros)
-before including the GLFW header.
-
-@code
-#define GLFW_INCLUDE_GLEXT
-#include <GLFW/glfw3.h>
-@endcode
-
-
-@subsubsection context_glext_string Checking for extensions
-
-A given machine may not actually support the extension (it may have older
-drivers or a graphics card that lacks the necessary hardware features), so it
-is necessary to check at run-time whether the context supports the extension.
-This is done with @ref glfwExtensionSupported.
-
-@code
-if (glfwExtensionSupported("GL_ARB_debug_output"))
-{
-    // The extension is supported by the current context
-}
-@endcode
-
-The argument is a null terminated ASCII string with the extension name.  If the
-extension is supported, @ref glfwExtensionSupported returns `GL_TRUE`, otherwise
-it returns `GL_FALSE`.
-
-
-@subsubsection context_glext_proc Fetching function pointers
-
-Many extensions, though not all, require the use of new OpenGL functions.
-These functions often do not have entry points in the client API libraries of
-your operating system, making it necessary to fetch them at run time.  You can
-retrieve pointers to these functions with @ref glfwGetProcAddress.
-
-@code
-PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = glfwGetProcAddress("glGetDebugMessageLogARB");
-@endcode
-
-In general, you should avoid giving the function pointer variables the (exact)
-same name as the function, as this may confuse your linker.  Instead, you can
-use a different prefix, like above, or some other naming scheme.
-
-Now that all the pieces have been introduced, here is what they might look like
-when used together.
-
-@code
-#define GLFW_INCLUDE_GLEXT
-#include <GLFW/glfw3.h>
-
-#define glGetDebugMessageLogARB pfnGetDebugMessageLog
-PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog;
-
-// Flag indicating whether the extension is supported
-int has_ARB_debug_output = 0;
-
-void load_extensions(void)
-{
-    if (glfwExtensionSupported("GL_ARB_debug_output"))
-    {
-        pfnGetDebugMessageLog = (PFNGLGETDEBUGMESSAGELOGARBPROC) glfwGetProcAddress("glGetDebugMessageLogARB");
-        if (pfnGetDebugMessageLog)
-        {
-            // Both the extension name and the function pointer are present
-            has_ARB_debug_output = 1;
-        }
-    }
-}
-
-void some_function(void)
-{
-    if (has_ARB_debug_output)
-    {
-        // Now the extension function can be called as usual
-        glGetDebugMessageLogARB(...);
-    }
-}
-@endcode

-@page input Input guide
- 
-@tableofcontents
-
-This guide introduces the input related functions of GLFW.  There are also
-guides for the other areas of GLFW.
-
- - @ref intro
- - @ref window
- - @ref context
- - @ref monitor
-
-GLFW provides many kinds of input.  While some can only be polled, like time, or
-only received via callbacks, like scrolling, there are those that provide both
-callbacks and polling.  Where a callback is provided, that is the recommended
-way to receive that kind of input.  The more you can use callbacks the less time
-your users' machines will need to spend polling.
-
-All input callbacks receive a window handle.  By using the
-[window user pointer](@ref window_userptr), you can access non-global structures
-or objects from your callbacks.
-
-To get a better feel for how the various events callbacks behave, run the
-`events` test program.  It register every callback supported by GLFW and prints
-out all arguments provided for every event, along with time and sequence
-information.
-
-
-@section events Event processing
-
-GLFW needs to communicate regularly with the window system both in order to
-receive events and to show that the application hasn't locked up.  Event
-processing must be done regularly while you have visible windows and is normally
-done each frame after [buffer swapping](@ref buffer_swap).
-
-There are two functions for processing pending events.  @ref glfwPollEvents,
-processes only those events that have already been received and then returns
-immediately.
-
-@code
-glfwPollEvents();
-@endcode
-
-This is the best choice when rendering continually, like most games do.
-
-If you only need to update the contents of the window when you receive new
-input, @ref glfwWaitEvents is a better choice.
-
-@code
-glfwWaitEvents();
-@endcode
-
-It puts the thread to sleep until at least one event has been received and then
-processes all received events.  This saves a great deal of CPU cycles and is
-useful for, for example, editing tools.  There must be at least one GLFW window
-for this function to sleep.
-
-If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from
-another thread by posting an empty event to the event queue with @ref
-glfwPostEmptyEvent.
-
-@code
-glfwPostEmptyEvent();
-@endcode
-
-Do not assume that callbacks will _only_ be called through either of the above
-functions.  While it is necessary to process events in the event queue, some
-window systems will send some events directly to the application, which in turn
-causes callbacks to be called outside of regular event processing.
-
-
-@section input_keyboard Keyboard input
-
-GLFW divides keyboard input into two categories; key events and character
-events.  Key events relate to actual physical keyboard keys, whereas character
-events relate to the Unicode code points generated by pressing some of them.
-
-Keys and characters do not map 1:1.  A single key press may produce several
-characters, and a single character may require several keys to produce.  This
-may not be the case on your machine, but your users are likely not all using the
-same keyboard layout, input method or even operating system as you.
-
-
-@subsection input_key Key input
-
-If you wish to be notified when a physical key is pressed or released or when it
-repeats, set a key callback.
-
-@code
-glfwSetKeyCallback(window, key_callback);
-@endcode
-
-The callback function receives the [keyboard key](@ref keys), platform-specific
-scancode, key action and [modifier bits](@ref mods).
-
-@code
-void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
-{
-    if (key == GLFW_KEY_E && action == GLFW_PRESS)
-        activate_airship();
-}
-@endcode
-
-The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`.  The key
-will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it.  These keys still
-have unique, if platform-specific scancodes.
-
-The scancode is unique for every key but is platform-specific, so a scancode
-will map to different keys on different platforms.
-
-The key will be `GLFW_KEY_UNKNOWN` for special keys like _E-mail_ or _Play_ that
-don't have a key token.  Those keys will still have unique, if platform-specific
-scancodes.
-
-Key states for [named keys](@ref keys) are also saved in per-window state arrays
-that can be polled with @ref glfwGetKey.
-
-@code
-int state = glfwGetKey(window, GLFW_KEY_E);
-if (state == GLFW_PRESS)
-    activate_airship();
-@endcode
-
-The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`.
-
-This function only returns cached key event state.  It does not poll the
-system for the current state of the key.
-
-Whenever you poll state, you risk missing the state change you are looking for.
-If a pressed key is released again before you poll its state, you will have
-missed the key press.  The recommended solution for this is to use a
-key callback, but there is also the `GLFW_STICKY_KEYS` input mode.
-
-@code
-glfwSetInputMode(window, GLFW_STICKY_KEYS, 1);
-@endcode
-
-When sticky keys mode is enabled, the pollable state of a key will remain
-`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey.  Once
-it has been polled, if a key release event had been processed in the meantime,
-the state will reset to `GLFW_RELEASE`, otherwise it will remain `GLFW_PRESS`.
-
-The `GLFW_KEY_LAST` constant holds the highest value of any
-[named key](@ref keys).
-
-
-@subsection input_char Text input
-
-GLFW supports text input in the form of a stream of
-[Unicode code points](https://en.wikipedia.org/wiki/Unicode), as produced by the
-operating system text input system.  Unlike key input, text input obeys keyboard
-layouts and modifier keys and supports composing characters using
-[dead keys](https://en.wikipedia.org/wiki/Dead_key).  Once received, you can
-encode the code points into
-[UTF-8](https://en.wikipedia.org/wiki/UTF-8) or any other encoding you prefer.
-
-Because an `unsigned int` is 32 bits long on all platforms supported by GLFW,
-you can treat the code point argument as native endian
-[UTF-32](https://en.wikipedia.org/wiki/UTF-32).
-
-There are two callbacks for receiving Unicode code points.  If you wish to
-offer regular text input, set a character callback.
-
-@code
-glfwSetCharCallback(window, character_callback);
-@endcode
-
-The callback function receives Unicode code points for key events that would
-have led to regular text input and generally behaves as a standard text field on
-that platform.
-
-@code
-void character_callback(GLFWwindow* window, unsigned int codepoint)
-{
-}
-@endcode
-
-If you wish to receive even those Unicode code points generated with modifier
-key combinations that a plain text field would ignore, or just want to know
-exactly what modifier keys were used, set a character with modifiers callback.
-
-@code
-glfwSetCharModsCallback(window, charmods_callback);
-@endcode
-
-The callback function receives Unicode code points and
-[modifier bits](@ref mods).
-
-@code
-void charmods_callback(GLFWwindow* window, unsigned int codepoint, int mods)
-{
-}
-@endcode
-
-
-@section input_mouse Mouse input
-
-Mouse input comes in many forms, including cursor motion, button presses and
-scrolling offsets.  The cursor appearance can also be changed, either to
-a custom image or a standard cursor shape from the system theme.
-
-
-@subsection cursor_pos Cursor position
-
-If you wish to be notified when the cursor moves over the window, set a cursor
-position callback.
-
-@code
-glfwSetCursorPosCallback(window, cursor_pos_callback);
-@endcode
-
-The callback functions receives the cursor position.  On platforms that provide
-it, the full sub-pixel cursor position is passed on.
-
-@code
-static void cursor_position_callback(GLFWwindow* window, double xpos, double ypos)
-{
-}
-@endcode
-
-The cursor position is also saved per-window and can be polled with @ref
-glfwGetCursorPos.
-
-@code
-double xpos, ypos;
-glfwGetCursorPos(window, &xpos, &ypos);
-@endcode
-
-
-@subsection cursor_mode Cursor modes
-
-The `GLFW_CURSOR` input mode provides several cursor modes for special forms of
-mouse motion input.  By default, the cursor mode is `GLFW_CURSOR_NORMAL`,
-meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor)
-is used and cursor motion is not limited.
-
-If you wish to implement mouse motion based camera controls or other input
-schemes that require unlimited mouse movement, set the cursor mode to
-`GLFW_CURSOR_DISABLED`.
-
-@code
-glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED);
-@endcode
-
-This will hide the cursor and lock it to the specified window.  GLFW will then
-take care of all the details of cursor re-centering and offset calculation and
-providing the application with a virtual cursor position.  This virtual position
-is provided normally via both the cursor position callback and through polling.
-
-@note You should not implement your own version of this functionality using
-other features of GLFW.  It is not supported and will not work as robustly as
-`GLFW_CURSOR_DISABLED`.
-
-If you just wish the cursor to become hidden when it is over a window, set
-the cursor mode to `GLFW_CURSOR_HIDDEN`.
-
-@code
-glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN);
-@endcode
-
-This mode puts no limit on the motion of the cursor.
-
-To exit out of either of these special modes, restore the `GLFW_CURSOR_NORMAL`
-cursor mode.
-
-@code
-glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_NORMAL);
-@endcode
-
-
-@subsection cursor_object Cursor objects
-
-GLFW supports creating both custom and system theme cursor images, encapsulated
-as @ref GLFWcursor objects.  They are created with @ref glfwCreateCursor or @ref
-glfwCreateStandardCursor and destroyed with @ref glfwDestroyCursor, or @ref
-glfwTerminate, if any remain.
-
-
-@subsubsection cursor_custom Custom cursor creation
-
-A custom cursor is created with @ref glfwCreateCursor, which returns a handle to
-the created cursor object.  For example, this creates a 16x16 white square
-cursor with the hot-spot in the upper-left corner:
-
-@code
-unsigned char pixels[16 * 16 * 4];
-memset(pixels, 0xff, sizeof(pixels));
-
-GLFWimage image;
-image.width = 16;
-image.height = 16;
-image.pixels = pixels;
-
-GLFWcursor* cursor = glfwCreateCursor(&image, 0, 0);
-@endcode
-
-If cursor creation fails, `NULL` will be returned, so it is necessary to check
-the return value.
-
-The image data is 32-bit RGBA, i.e. eight bits per channel.  The pixels are
-arranged canonically as sequential rows, starting from the top-left corner.
-
-
-@subsubsection cursor_standard Standard cursor creation
-
-A cursor with a [standard shape](@ref shapes) from the current system cursor
-theme can be can be created with @ref glfwCreateStandardCursor.
-
-@code
-GLFWcursor* cursor = glfwCreateStandardCursor(GLFW_HRESIZE_CURSOR);
-@endcode
-
-These cursor objects behave in the exact same way as those created with @ref
-glfwCreateCursor except that the system cursor theme provides the actual image.
-
-
-@subsubsection cursor_destruction Cursor destruction
-
-When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor.
-
-@code
-glfwDestroyCursor(cursor);
-@endcode
-
-Cursor destruction always succeeds.  All cursors remaining when @ref
-glfwTerminate is called are destroyed as well.
-
-
-@subsubsection cursor_set Cursor setting
-
-A cursor can be set as current for a window with @ref glfwSetCursor.
-
-@code
-glfwSetCursor(window, cursor);
-@endcode
-
-Once set, the cursor image will be used as long as the system cursor is over the
-client area of the window and the [cursor mode](@ref cursor_mode) is set
-to `GLFW_CURSOR_NORMAL`.
-
-A single cursor may be set for any number of windows.
-
-To remove a cursor from a window, set the cursor of that window to `NULL`.
-
-@code
-glfwSetCursor(window, NULL);
-@endcode
-
-When a cursor is destroyed, it is removed from any window where it is set.  This
-does not affect the cursor modes of those windows.
-
-
-@subsection cursor_enter Cursor enter/leave events
-
-If you wish to be notified when the cursor enters or leaves the client area of
-a window, set a cursor enter/leave callback.
-
-@code
-glfwSetCursorEnterCallback(window, cursor_enter_callback);
-@endcode
-
-The callback function receives the new classification of the cursor.
-
-@code
-void cursor_enter_callback(GLFWwindow* window, int entered)
-{
-    if (entered)
-    {
-        // The cursor entered the client area of the window
-    }
-    else
-    {
-        // The cursor left the client area of the window
-    }
-}
-@endcode
-
-
-@subsection input_mouse_button Mouse button input
-
-If you wish to be notified when a mouse button is pressed or released, set
-a mouse button callback.
-
-@code
-glfwSetMouseButtonCallback(window, mouse_button_callback);
-@endcode
-
-The callback function receives the [mouse button](@ref buttons), button action
-and [modifier bits](@ref mods).
-
-@code
-void mouse_button_callback(GLFWwindow* window, int button, int action, int mods)
-{
-    if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS)
-        popup_menu();
-}
-@endcode
-
-The action is one of `GLFW_PRESS` or `GLFW_RELEASE`.
-
-Mouse button states for [named buttons](@ref buttons) are also saved in
-per-window state arrays that can be polled with @ref glfwGetMouseButton.
-
-@code
-int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT);
-if (state == GLFW_PRESS)
-    upgrade_cow();
-@endcode
-
-The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`.
-
-This function only returns cached mouse button event state.  It does not poll
-the system for the current state of the mouse button.
-
-Whenever you poll state, you risk missing the state change you are looking for.
-If a pressed mouse button is released again before you poll its state, you will have
-missed the button press.  The recommended solution for this is to use a
-mouse button callback, but there is also the `GLFW_STICKY_MOUSE_BUTTONS`
-input mode.
-
-@code
-glfwSetInputMode(window, GLFW_STICKY_MOUSE_BUTTONS, 1);
-@endcode
-
-When sticky mouse buttons mode is enabled, the pollable state of a mouse button
-will remain `GLFW_PRESS` until the state of that button is polled with @ref
-glfwGetMouseButton.  Once it has been polled, if a mouse button release event
-had been processed in the meantime, the state will reset to `GLFW_RELEASE`,
-otherwise it will remain `GLFW_PRESS`.
-
-The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any
-[named button](@ref buttons).
-
-
-@subsection scrolling Scroll input
-
-If you wish to be notified when the user scrolls, whether with a mouse wheel or
-touchpad gesture, set a scroll callback.
-
-@code
-glfwSetScrollCallback(window, scroll_callback);
-@endcode
-
-The callback function receives two-dimensional scroll offsets.
-
-@code
-void scroll_callback(GLFWwindow* window, double xoffset, double yoffset)
-{
-}
-@endcode
-
-A simple mouse wheel, being vertical, provides offsets along the Y-axis.
-
-
-@section joystick Joystick input
-
-The joystick functions expose connected joysticks and controllers, with both
-referred to as joysticks.  It supports up to sixteen joysticks, ranging from
-`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to `GLFW_JOYSTICK_LAST`.  You can test
-whether a [joystick](@ref joysticks) is present with @ref glfwJoystickPresent.
-
-@code
-int present = glfwJoystickPresent(GLFW_JOYSTICK_1);
-@endcode
-
-When GLFW is initialized, detected joysticks are added to to the beginning of
-the array, starting with `GLFW_JOYSTICK_1`.  Once a joystick is detected, it
-keeps its assigned index until it is disconnected, so as joysticks are connected
-and disconnected, they will become spread out.
-
-Joystick state is updated as needed when a joystick function is called and does
-not require a window to be created or @ref glfwPollEvents or @ref glfwWaitEvents
-to be called.
-
-
-@subsection joystick_axis Joystick axis states
-
-The positions of all axes of a joystick are returned by @ref
-glfwGetJoystickAxes.  See the reference documentation for the lifetime of the
-returned array.
-
-@code
-int count;
-const float* axes = glfwGetJoystickAxes(GLFW_JOYSTICK_1, &count);
-@endcode
-
-Each element in the returned array is a value between -1.0 and 1.0.
-
-
-@subsection joystick_button Joystick button states
-
-The states of all buttons of a joystick are returned by @ref
-glfwGetJoystickButtons.  See the reference documentation for the lifetime of the
-returned array.
-
-@code
-int count;
-const unsigned char* axes = glfwGetJoystickButtons(GLFW_JOYSTICK_1, &count);
-@endcode
-
-Each element in the returned array is either `GLFW_PRESS` or `GLFW_RELEASE`.
-
-
-@subsection joystick_name Joystick name
-
-The human-readable, UTF-8 encoded name of a joystick is returned by @ref
-glfwGetJoystickName.  See the reference documentation for the lifetime of the
-returned string.           
-
-@code
-const char* name = glfwGetJoystickName(GLFW_JOYSTICK_1);
-@endcode
-
-Joystick names are not guaranteed to be unique.  Two joysticks of the same model
-and make may have the same name.  Only the [joystick token](@ref joysticks) is
-guaranteed to be unique, and only until that joystick is disconnected.
-
-
-@section time Time input
-
-GLFW provides high-resolution time input, in seconds, with @ref glfwGetTime.
-
-@code
-double seconds = glfwGetTime();
-@endcode
-
-It returns the number of seconds since the timer was started when the library
-was initialized with @ref glfwInit.  The platform-specific time sources used
-usually have micro- or nanosecond resolution.
-
-You can modify the reference time with @ref glfwSetTime.
-
-@code
-glfwSetTime(4.0);
-@endcode
-
-This sets the timer to the specified time, in seconds.
-
-
-@section clipboard Clipboard input and output
-
-If the system clipboard contains a UTF-8 encoded string or if it can be
-converted to one, you can retrieve it with @ref glfwGetClipboardString.  See the
-reference documentation for the lifetime of the returned string.
-
-@code
-const char* clipboard = glfwGetClipboardString(window);
-@endcode
-
-The contents of the system clipboard can be set to a UTF-8 encoded string with
-@ref glfwSetClipboardString.
-
-@code
-glfwSetClipboardString(window, "A string with words in it");
-@endcode
-
-The clipboard functions take a window handle argument because some window
-systems require a window to communicate with the system clipboard.  Any valid
-window may be used.
-
-
-@section path_drop Path drop input
-
-If you wish to receive the paths of files and/or directories dropped on
-a window, set a file drop callback.
-
-@code
-glfwSetDropCallback(window, drop_callback);
-@endcode
-
-The callback function receives an array of paths encoded as UTF-8.
-
-@code
-void drop_callback(GLFWwindow* window, int count, const char** paths)
-{
-    int i;
-    for (i = 0;  i < count;  i++)
-        handle_dropped_file(paths[i]);
-}
-@endcode
-
-The path array and its strings are only valid until the file drop callback
-returns, as they may have been generated specifically for that event.  You need
-to make a deep copy of the array if you want to keep the paths.

-@page internals Internal structure
-
-@tableofcontents
-
-There are several interfaces inside GLFW.  Each interface has its own area of
-responsibility and its own naming conventions.
-
-
-@section internals_public Public interface
-
-The most well-known is the public interface, described in the glfw3.h header
-file.  This is implemented in source files shared by all platforms and these
-files contain no platform-specific code.  This code usually ends up calling the
-platform and internal interfaces to do the actual work.
-
-The public interface uses the OpenGL naming conventions except with GLFW and
-glfw instead of GL and gl.  For struct members, where OpenGL sets no precedent,
-it use headless camel case.
-
-Examples: @ref glfwCreateWindow, @ref GLFWwindow, @ref GLFWvidmode.redBits,
-`GLFW_RED_BITS`
-
-
-@section internals_native Native interface
-
-The [native interface](@ref native) is a small set of publicly available
-but platform-specific functions, described in the glfw3native.h header file and
-used to gain access to the underlying window, context and (on some platforms)
-display handles used by the platform interface.
-
-The function names of the native interface are similar to those of the public
-interface, but embeds the name of the interface that the returned handle is
-from.
-
-Examples: @ref glfwGetX11Window, @ref glfwGetWGLContext
-
-
-@section internals_internal Internal interface
-
-The internal interface consists of utility functions used by all other
-interfaces.  It is shared code implemented in the same shared source files as
-the public and event interfaces.  The internal interface is described in the
-internal.h header file.
-
-The internal interface is in charge of GLFW's global data, which it stores in
-a `_GLFWlibrary` struct named `_glfw`.
-
-The internal interface uses the same style as the public interface, except all
-global names have a leading underscore.
-
-Examples: @ref _glfwIsValidContextConfig, @ref _GLFWwindow, `_glfw.currentRamp`
-
-
-@section internals_platform Platform interface
-
-The platform interface implements all platform-specific operations as a service
-to the public interface.  This includes event processing.  The platform
-interface is never directly called by application code and never directly calls
-application-provided callbacks.  It is also prohibited from modifying the
-platform-independent part of the internal structs.  Instead, it calls the event
-interface when events interesting to GLFW are received.
-
-The platform interface mirrors those parts of the public interface that needs to
-perform platform-specific operations on some or all platforms.  The are also
-named the same except that the glfw function prefix is replaced by
-_glfwPlatform.
-
-Examples: @ref _glfwPlatformCreateWindow
-
-The platform interface also defines structs that contain platform-specific
-global and per-object state.  Their names mirror those of the internal
-interface, except that an interface-specific suffix is added.
-
-Examples: `_GLFWwindowX11`, `_GLFWcontextWGL`
-
-These structs are incorporated as members into the internal interface structs
-using special macros that name them after the specific interface used.  This
-prevents shared code from accidentally using these members.
-
-Examples: `window.win32.handle`, `_glfw.x11.display`
-
-
-@section internals_event Event interface
-
-The event interface is implemented in the same shared source files as the public
-interface and is responsible for delivering the events it receives to the
-application, either via callbacks, via window state changes or both.
-
-The function names of the event interface use a `_glfwInput` prefix and the
-ObjectEvent pattern.
-
-Examples: @ref _glfwInputWindowFocus, @ref _glfwInputCursorMotion
-
-
-@section internals_static Static functions
-
-Static functions may be used by any interface and have no prefixes or suffixes.
-These use headless camel case.
-
-Examples: `clearScrollOffsets`
-
-
-@section internals_config Configuration macros
-
-GLFW uses a number of configuration macros to select at compile time which
-interfaces and code paths to use.  They are defined in the glfw_config.h header file,
-which is generated from the `glfw_config.h.in` file by CMake.
-
-Configuration macros the same style as tokens in the public interface, except
-with a leading underscore.
-
-Examples: `_GLFW_HAS_GLXGETPROCADDRESS`

-@page intro Introduction to the API
- 
-@tableofcontents
-
-This guide introduces the basic concepts of GLFW and describes initialization,
-error handling and API guarantees and limitations.  For a broad but shallow
-tutorial, see @ref quick instead.  There are also guides for the other areas of
-GLFW.
-
- - @ref window
- - @ref context
- - @ref monitor
- - @ref input
-
-
-@section intro_init Initialization and termination
-
-Before most GLFW functions may be called, the library must be initialized.
-This initialization checks what features are available on the machine,
-enumerates monitors and joysticks, initializes the timer and performs any
-required platform-specific initialization.
-
-Only the following functions may be called before the library has been
-successfully initialized, and only from the main thread.
-
- - @ref glfwGetVersion
- - @ref glfwGetVersionString
- - @ref glfwSetErrorCallback
- - @ref glfwInit
- - @ref glfwTerminate
-
-Calling any other function before that time will cause a @ref
-GLFW_NOT_INITIALIZED error. 
-
-
-@subsection intro_init_init Initializing GLFW
-
-The library is initialized with @ref glfwInit, which returns `GL_FALSE` if an
-error occurred.
-
-@code
-if (!glfwInit())
-{
-    // Handle initialization failure
-}
-@endcode
-
-If any part of initialization fails, all remaining bits are terminated as if
-@ref glfwTerminate was called.  The library only needs to be initialized once
-and additional calls to an already initialized library will simply return
-`GL_TRUE` immediately.
-
-Once the library has been successfully initialized, it should be terminated
-before the application exits.
-
-
-@subsection intro_init_terminate Terminating GLFW
-
-Before your application exits, you should terminate the GLFW library if it has
-been initialized.  This is done with @ref glfwTerminate.
-
-@code
-glfwTerminate();
-@endcode
-
-This will destroy any remaining window, monitor and cursor objects, restore any
-modified gamma ramps, re-enable the screensaver if it had been disabled and free
-any resources allocated by GLFW.
-
-Once the library is terminated, it is as if it had never been initialized and
-you will need to initialize it again before being able to use GLFW.  If the
-library was not initialized or had already been terminated, it return
-immediately. 
-
-
-@section error_handling Error handling
-
-Some GLFW functions have return values that indicate an error, but this is often
-not very helpful when trying to figure out _why_ the error occurred.  Some
-functions also return otherwise valid values on error.  Finally, far from all
-GLFW functions have return values.
-
-This is where the error callback comes in.  This callback is called whenever an
-error occurs.  It is set with @ref glfwSetErrorCallback, a function that may be
-called regardless of whether GLFW is initialized.
-
-@code
-glfwSetErrorCallback(error_callback);
-@endcode
-
-The error callback receives a human-readable description of the error and (when
-possible) its cause.  The description encoded as UTF-8.  The callback is also
-provided with an [error code](@ref errors). 
-
-@code
-void error_callback(int error, const char* description)
-{
-    puts(description);
-}
-@endcode
-
-The error code indicates the general category of the error.  Some error codes,
-such as @ref GLFW_NOT_INITIALIZED has only a single meaning, whereas others like
-@ref GLFW_PLATFORM_ERROR are used for many different errors.
-
-The description string is only valid until the error callback returns, as it may
-have been generated specifically for that error.  This lets GLFW provide much
-more specific error descriptions but means you must make a copy if you want to
-keep the description string.
-
-
-@section coordinate_systems Coordinate systems
-
-GLFW has two primary coordinate systems: the _virtual screen_ and the window
-_client area_ or _content area_.  Both use the same unit: _virtual screen
-coordinates_, or just _screen coordinates_, which don't necessarily correspond
-to pixels.
-
-<img src="spaces.svg" width="90%" />
-
-Both the virtual screen and the client area coordinate systems have the X-axis
-pointing to the right and the Y-axis pointing down.
-
-Window and monitor positions are specified as the position of the upper-left
-corners of their content areas relative to the virtual screen, while cursor
-positions are specified relative to a window's client area.
-
-Because the origin of the window's client area coordinate system is also the
-point from which the window position is specified, you can translate client area
-coordinates to the virtual screen by adding the window position.  The window
-frame, when present, extends out from the client area but does not affect the
-window position.
-
-Almost all positions and sizes in GLFW are measured in screen coordinates
-relative to one of the two origins above.  This includes cursor positions,
-window positions and sizes, window frame sizes, monitor positions and video mode
-resolutions.
-
-Two exceptions are the [monitor physical size](@ref monitor_size), which is
-measured in millimetres, and [framebuffer size](@ref window_fbsize), which is
-measured in pixels.
-
-Pixels and screen coordinates may map 1:1 on your machine, but they won't on
-every other machine, for example on a Mac with a Retina display.  The ratio
-between screen coordinates and pixels may also change at run-time depending on
-which monitor the window is currently considered to be on.
-
-
-@section guarantees_limitations Guarantees and limitations
-
-This section describes the conditions under which GLFW can be expected to
-function, barring bugs in the operating system or drivers.  Use of GLFW outside
-of these limits may work on some platforms, or on some machines, or some of the
-time, or on some versions of GLFW, but it may break at any time and this will
-not be considered a bug.
-
-
-@subsection lifetime Pointer lifetimes
-
-GLFW will never free any pointer you provide to it and you must never free any
-pointer it provides to you.
-
-Many GLFW functions return pointers to dynamically allocated structures, strings
-or arrays, and some callbacks are provided with strings or arrays.  These are
-always managed by GLFW and should never be freed by the application.  The
-lifetime of these pointers is documented for each GLFW function and callback.
-If you need to keep this data, you must copy it before its lifetime expires.
-
-Many GLFW functions accept pointers to structures or strings allocated by the
-application.  These are never freed by GLFW and are always the responsibility of
-the application.  If GLFW needs to keep the data in these structures or strings,
-it is copied before the function returns.
-
-Pointer lifetimes are guaranteed not to be shortened in future minor or patch
-releases.
-
-
-@subsection reentrancy Reentrancy
-
-GLFW event processing and object creation and destruction are not reentrant.
-This means that the following functions may not be called from any callback
-function:
-
- - @ref glfwCreateWindow
- - @ref glfwDestroyWindow
- - @ref glfwCreateCursor
- - @ref glfwCreateStandardCursor
- - @ref glfwDestroyCursor
- - @ref glfwPollEvents
- - @ref glfwWaitEvents
- - @ref glfwTerminate
-
-These functions may be made reentrant in future minor or patch releases, but
-functions not on this list will not be made non-reentrant.
-
-
-@subsection thread_safety Thread safety
-
-Most GLFW functions may only be called from the main thread, but some may be
-called from any thread.  However, no GLFW function may be called from any other
-thread until GLFW has been successfully initialized on the main thread,
-including functions that may called before initialization.
-
-The reference documentation for every GLFW function states whether it is limited
-to the main thread.                                                        
-
-The following categories of functions are and will remain limited to the main
-thread due to the limitations of one or several platforms:
-
- - Initialization and termination
- - Event processing
- - Creation and destruction of window, context and cursor objects
-
-Because event processing must be performed on the main thread, all callbacks
-except for the error callback will only be called on that thread.  The error
-callback may be called on any thread, as any GLFW function may generate errors.
-
-The posting of empty events may be done from any thread.  The window user
-pointer and close flag may also be accessed and modified from any thread, but
-this is not synchronized by GLFW.  The following window related functions may
-be called from any thread:
-
- - @ref glfwPostEmptyEvent
- - @ref glfwGetWindowUserPointer
- - @ref glfwSetWindowUserPointer
- - @ref glfwWindowShouldClose
- - @ref glfwSetWindowShouldClose
-
-Rendering may be done on any thread.  The following context related functions
-may be called from any thread:
-
- - @ref glfwMakeContextCurrent
- - @ref glfwGetCurrentContext
- - @ref glfwSwapBuffers
- - @ref glfwSwapInterval
- - @ref glfwExtensionSupported
- - @ref glfwGetProcAddress
-
-The timer may be accessed from any thread, but this is not synchronized by GLFW.
-The following timer related functions may be called from any thread:        
-
- - @ref glfwGetTime
-
-Library version information may be queried from any thread.  The following
-version related functions may be called from any thread:
-
- - @ref glfwGetVersion
- - @ref glfwGetVersionString
-
-GLFW uses no synchronization objects internally except for thread-local storage
-to keep track of the current context for each thread.  Synchronization is left
-to the application.
-
-Functions that may currently be called from any thread will always remain so,
-but functions that are currently limited to the main may be updated to allow
-calls from any thread in future releases.
-
-
-@subsection compatibility Version compatibility
-
-GLFW guarantees binary backward compatibility with earlier minor versions of the
-API.  This means that you can drop in a newer version of the GLFW DLL / shared
-library / dynamic library and existing applications will continue to run.
-
-Once a function or constant has been added, the signature of that function or
-value of that constant will remain unchanged until the next major version of
-GLFW.  No compatibility of any kind is guaranteed between major versions.
-
-Undocumented behavior, i.e. behavior that is not described in the documentation,
-may change at any time until it is documented.
-
-If the reference documentation and the implementation differ, the reference
-documentation is correct and the implementation will be fixed in the next
-release.
-
-
-@subsection event_order Event order
-
-The order of arrival of related events is not guaranteed to be consistent
-across platforms.  The exception is synthetic key and mouse button release
-events, which are always delivered after the window defocus event.
-
-
-@section intro_version Version management
-
-GLFW provides mechanisms for identifying what version of GLFW your application
-was compiled against as well as what version it is currently running against.
-If you are loading GLFW dynamically (not just linking dynamically), you can use
-this to verify that the library binary is compatible with your application.
-
-
-@subsection intro_version_compile Compile-time version
-
-The compile-time version of GLFW is provided by the GLFW header with the
-`GLFW_VERSION_MAJOR`, `GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` macros.
-
-@code
-printf("Compiled against GLFW %i.%i.%i\n",
-       GLFW_VERSION_MAJOR,
-       GLFW_VERSION_MINOR,
-       GLFW_VERSION_REVISION);
-@endcode
-
-
-@subsection intro_version_runtime Run-time version
-
-The run-time version can be retrieved with @ref glfwGetVersion, a function that
-may be called regardless of whether GLFW is initialized.
-
-@code
-int major, minor, revision;
-glfwGetVersion(&major, &minor, &revision);
-
-printf("Running against GLFW %i.%i.%i\n", major, minor, revision);
-@endcode
-
-
-@subsection intro_version_string Version string
-
-GLFW 3 also provides a compile-time generated version string that describes the
-version, platform, compiler and any platform-specific compile-time options.
-This is primarily intended for submitting bug reports, to allow developers to
-see which code paths are enabled in a binary.
-
-The version string is returned by @ref glfwGetVersionString, a function that may
-be called regardless of whether GLFW is initialized.
-
-__Do not use the version string__ to parse the GLFW library version.  The @ref
-glfwGetVersion function already provides the version of the running library
-binary.
-
-The format of the string is as follows:
- - The version of GLFW
- - The name of the window system API
- - The name of the context creation API
- - Any additional options or APIs
-
-For example, when compiling GLFW 3.0 with MinGW using the Win32 and WGL
-back ends, the version string may look something like this:
-
-@code
-3.0.0 Win32 WGL MinGW
-@endcode

- - @ref context
- - @ref input
-
-
-@section monitor_object Monitor objects
-
-A monitor object represents a currently connected monitor and is represented as
-a pointer to the [opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type
-@ref GLFWmonitor.  Monitor objects cannot be created or destroyed by the
-application and retain their addresses until the monitors they represent are
-disconnected or until the library is [terminated](@ref intro_init_terminate).
-
-Each monitor has a current video mode, a list of supported video modes,
-a virtual position, a human-readable name, an estimated physical size and
-a gamma ramp.  One of the monitors is the primary monitor.
-
-The virtual position of a monitor is in
-[screen coordinates](@ref coordinate_systems) and, together with the current
-video mode, describes the viewports that the connected monitors provide into the
-virtual desktop that spans them.
-
-To see how GLFW views your monitor setup and its available video modes, run the
-`modes` test program.
-
-
-@subsection monitor_monitors Retrieving monitors
-
-The primary monitor is returned by @ref glfwGetPrimaryMonitor.  It is the user's
-preferred monitor and is usually the one with global UI elements like task bar
-or menu bar.
-
-@code
-GLFWmonitor* primary = glfwGetPrimaryMonitor();
-@endcode
-
-You can retrieve all currently connected monitors with @ref glfwGetMonitors.
-See the reference documentation for the lifetime of the returned array.
-
-@code
-int count;
-GLFWmonitor** monitors = glfwGetMonitors(&count);
-@endcode
-
-The primary monitor is always the first monitor in the returned array, but other
-monitors may be moved to a different index when a monitor is connected or
-disconnected.
-
-
-@subsection monitor_event Monitor configuration changes
-
-If you wish to be notified when a monitor is connected or disconnected, set
-a monitor callback.
-
-@code
-glfwSetMonitorCallback(monitor_callback);
-@endcode
-
-The callback function receives the handle for the monitor that has been
-connected or disconnected and a monitor action.
-
-@code
-void monitor_callback(GLFWmonitor* monitor, int event)
-{
-}
-@endcode
-
-The action is one of `GLFW_CONNECTED` or `GLFW_DISCONNECTED`.
-
-
-@section monitor_properties Monitor properties
-
-Each monitor has a current video mode, a list of supported video modes,
-a virtual position, a human-readable name, an estimated physical size and
-a gamma ramp.
-
-
-@subsection monitor_modes Video modes
-
-GLFW generally does a good job selecting a suitable video mode when you create
-a full screen window, but it is sometimes useful to know exactly which video
-modes are supported.
-
-Video modes are represented as @ref GLFWvidmode structures.  You can get an
-array of the video modes supported by a monitor with @ref glfwGetVideoModes.
-See the reference documentation for the lifetime of the returned array.
-
-@code
-int count;
-GLFWvidmode* modes = glfwGetVideoModes(monitor, &count);
-@endcode
-
-To get the current video mode of a monitor call @ref glfwGetVideoMode.  See the
-reference documentation for the lifetime of the returned pointer.
-
-@code
-const GLFWvidmode* mode = glfwGetVideoMode(monitor);
-@endcode
-
-The resolution of a video mode is specified in
-[screen coordinates](@ref coordinate_systems), not pixels.
-
-
-@subsection monitor_size Physical size
-
-The physical size of a monitor in millimetres, or an estimation of it, can be
-retrieved with @ref glfwGetMonitorPhysicalSize.  This has no relation to its
-current _resolution_, i.e. the width and height of its current
-[video mode](@ref monitor_modes).
-
-@code
-int widthMM, heightMM;
-glfwGetMonitorPhysicalSize(monitor, &widthMM, &heightMM);
-@endcode
-
-This can, for example, be used together with the current video mode to calculate
-the DPI of a monitor. 
-
-@code
-const double dpi = mode->width / (widthMM / 25.4);
-@endcode
-
-
-@subsection monitor_pos Virtual position
-
-The position of the monitor on the virtual desktop, in
-[screen coordinates](@ref coordinate_systems), can be retrieved with @ref
-glfwGetMonitorPos.
-
-@code
-int xpos, ypos;
-glfwGetMonitorPos(monitor, &xpos, &ypos);
-@endcode
-
-
-@subsection monitor_name Human-readable name
-
-The human-readable, UTF-8 encoded name of a monitor is returned by @ref
-glfwGetMonitorName.  See the reference documentation for the lifetime of the
-returned string.
-
-@code
-const char* name = glfwGetMonitorName(monitor);
-@endcode
-
-Monitor names are not guaranteed to be unique.  Two monitors of the same model
-and make may have the same name.  Only the monitor handle is guaranteed to be
-unique, and only until that monitor is disconnected.
-
-
-@subsection monitor_gamma Gamma ramp
-
-The gamma ramp of a monitor can be set with @ref glfwSetGammaRamp, which accepts
-a monitor handle and a pointer to a @ref GLFWgammaramp structure.
-
-@code
-GLFWgammaramp ramp;
-unsigned short red[256], green[256], blue[256];

-@page moving Moving from GLFW 2 to 3
-
-@tableofcontents
-
-This is a transition guide for moving from GLFW 2 to 3.  It describes what has
-changed or been removed, but does _not_ include
-[new features](@ref news) unless they are required when moving an existing code
-base onto the new API.  For example, the new multi-monitor functions are
-required to create full screen windows with GLFW 3.
-
-
-@section moving_removed Changed and removed features
-
-@subsection moving_renamed_files Renamed library and header file
-
-The GLFW 3 header is named @ref glfw3.h and moved to the `GLFW` directory, to
-avoid collisions with the headers of other major versions.  Similarly, the GLFW
-3 library is named `glfw3,` except when it's installed as a shared library on
-Unix-like systems, where it uses the
-[soname](https://en.wikipedia.org/wiki/soname) `libglfw.so.3`.
-
-@par Old syntax
-@code
-#include <GL/glfw.h>
-@endcode
-
-@par New syntax
-@code
-#include <GLFW/glfw3.h>
-@endcode
-
-
-@subsection moving_threads Removal of threading functions
-
-The threading functions have been removed, including the per-thread sleep
-function.  They were fairly primitive, under-used, poorly integrated and took
-time away from the focus of GLFW (i.e.  context, input and window).  There are
-better threading libraries available and native threading support is available
-in both [C++11](http://en.cppreference.com/w/cpp/thread) and
-[C11](http://en.cppreference.com/w/c/thread), both of which are gaining
-traction. 
-
-If you wish to use the C++11 or C11 facilities but your compiler doesn't yet
-support them, see the
-[TinyThread++](https://gitorious.org/tinythread/tinythreadpp) and
-[TinyCThread](https://github.com/tinycthread/tinycthread) projects created by
-the original author of GLFW.  These libraries implement a usable subset of the
-threading APIs in C++11 and C11, and in fact some GLFW 3 test programs use
-TinyCThread.
-
-However, GLFW 3 has better support for _use from multiple threads_ than GLFW
-2 had.  Contexts can be made current on any thread, although only a single
-thread at a time, and the documentation explicitly states which functions may be
-used from any thread and which may only be used from the main thread.
-
-@par Removed functions
-`glfwSleep`, `glfwCreateThread`, `glfwDestroyThread`, `glfwWaitThread`,
-`glfwGetThreadID`, `glfwCreateMutex`, `glfwDestroyMutex`, `glfwLockMutex`,
-`glfwUnlockMutex`, `glfwCreateCond`, `glfwDestroyCond`, `glfwWaitCond`,
-`glfwSignalCond`, `glfwBroadcastCond` and `glfwGetNumberOfProcessors`.
-
-
-@subsection moving_image Removal of image and texture loading
-
-The image and texture loading functions have been removed.  They only supported
-the Targa image format, making them mostly useful for beginner level examples.
-To become of sufficiently high quality to warrant keeping them in GLFW 3, they
-would need not only to support other formats, but also modern extensions to
-OpenGL texturing.  This would either add a number of external
-dependencies (libjpeg, libpng, etc.), or force GLFW to ship with inline versions
-of these libraries. 
-
-As there already are libraries doing this, it is unnecessary both to duplicate
-the work and to tie the duplicate to GLFW.  The resulting library would also be
-platform-independent, as both OpenGL and stdio are available wherever GLFW is.
-
-@par Removed functions
-`glfwReadImage`, `glfwReadMemoryImage`, `glfwFreeImage`, `glfwLoadTexture2D`,
-`glfwLoadMemoryTexture2D` and `glfwLoadTextureImage2D`.
-
-
-@subsection moving_stdcall Removal of GLFWCALL macro
-
-The `GLFWCALL` macro, which made callback functions use
-[__stdcall](http://msdn.microsoft.com/en-us/library/zxk0tw93.aspx) on Windows,
-has been removed.  GLFW is written in C, not Pascal.  Removing this macro means
-there's one less thing for application programmers to remember, i.e. the
-requirement to mark all callback functions with `GLFWCALL`.  It also simplifies
-the creation of DLLs and DLL link libraries, as there's no need to explicitly
-disable `@n` entry point suffixes. 
-
-@par Old syntax
-@code
-void GLFWCALL callback_function(...);
-@endcode
-
-@par New syntax
-@code
-void callback_function(...);
-@endcode
-
-
-@subsection moving_window_handles Window handle parameters
-
-Because GLFW 3 supports multiple windows, window handle parameters have been
-added to all window-related GLFW functions and callbacks.  The handle of
-a newly created window is returned by @ref glfwCreateWindow (formerly
-`glfwOpenWindow`).  Window handles are pointers to the
-[opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type @ref GLFWwindow.
-
-@par Old syntax
-@code
-glfwSetWindowTitle("New Window Title");
-@endcode
-
-@par New syntax
-@code
-glfwSetWindowTitle(window, "New Window Title");
-@endcode
-
-
-@subsection moving_monitor Explicit monitor selection
-
-GLFW 3 provides support for multiple monitors.  To request a full screen mode window,
-instead of passing `GLFW_FULLSCREEN` you specify which monitor you wish the
-window to use.  The @ref glfwGetPrimaryMonitor function returns the monitor that
-GLFW 2 would have selected, but there are many other
-[monitor functions](@ref monitor).  Monitor handles are pointers to the
-[opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type @ref GLFWmonitor.
-
-@par Old basic full screen
-@code
-glfwOpenWindow(640, 480, 8, 8, 8, 0, 24, 0, GLFW_FULLSCREEN);
-@endcode
-
-@par New basic full screen
-@code
-window = glfwCreateWindow(640, 480, "My Window", glfwGetPrimaryMonitor(), NULL);
-@endcode
-
-@note The framebuffer bit depth parameters of `glfwOpenWindow` have been turned
-into [window hints](@ref window_hints), but as they have been given
-[sane defaults](@ref window_hints_values) you rarely need to set these hints.
-
-
-@subsection moving_autopoll Removal of automatic event polling
-
-GLFW 3 does not automatically poll for events in @ref glfwSwapBuffers, meaning
-you need to call @ref glfwPollEvents or @ref glfwWaitEvents yourself.  Unlike
-buffer swap, which acts on a single window, the event processing functions act
-on all windows at once.
-
-@par Old basic main loop
-@code
-while (...)
-{
-    // Process input
-    // Render output
-    glfwSwapBuffers();
-}
-@endcode
-
-@par New basic main loop
-@code
-while (...)
-{
-    // Process input
-    // Render output
-    glfwSwapBuffers(window);
-    glfwPollEvents();
-}
-@endcode
-
-
-@subsection moving_context Explicit context management
-
-Each GLFW 3 window has its own OpenGL context and only you, the application
-programmer, can know which context should be current on which thread at any
-given time.  Therefore, GLFW 3 leaves that decision to you.
-
-This means that you need to call @ref glfwMakeContextCurrent after creating
-a window before you can call any OpenGL functions.
-
-
-@subsection moving_hidpi Separation of window and framebuffer sizes
-
-Window positions and sizes now use screen coordinates, which may not be the same
-as pixels on machines with high-DPI monitors.  This is important as OpenGL uses
-pixels, not screen coordinates.  For example, the rectangle specified with
-`glViewport` needs to use pixels.  Therefore, framebuffer size functions have
-been added.  You can retrieve the size of the framebuffer of a window with @ref
-glfwGetFramebufferSize function.  A framebuffer size callback has also been
-added, which can be set with @ref glfwSetFramebufferSizeCallback.
-
-@par Old basic viewport setup
-@code
-glfwGetWindowSize(&width, &height);
-glViewport(0, 0, width, height);
-@endcode
-
-@par New basic viewport setup
-@code
-glfwGetFramebufferSize(window, &width, &height);
-glViewport(0, 0, width, height);
-@endcode
-
-
-@subsection moving_window_close Window closing changes
-
-The `GLFW_OPENED` window parameter has been removed.  As long as the window has
-not been destroyed, whether through @ref glfwDestroyWindow or @ref
-glfwTerminate, the window is "open".
-
-A user attempting to close a window is now just an event like any other.  Unlike
-GLFW 2, windows and contexts created with GLFW 3 will never be destroyed unless
-you choose them to be.  Each window now has a close flag that is set to
-`GL_TRUE` when the user attempts to close that window.  By default, nothing else
-happens and the window stays visible.  It is then up to you to either destroy
-the window, take some other action or simply ignore the request.
-
-You can query the close flag at any time with @ref glfwWindowShouldClose and set
-it at any time with @ref glfwSetWindowShouldClose.
-
-@par Old basic main loop
-@code
-while (glfwGetWindowParam(GLFW_OPENED))
-{
-    ...
-}
-@endcode
-
-@par New basic main loop
-@code
-while (!glfwWindowShouldClose(window))
-{
-    ...
-}
-@endcode
-
-The close callback no longer returns a value.  Instead, it is called after the
-close flag has been set so it can override its value, if it chooses to, before
-event processing completes.  You may however not call @ref glfwDestroyWindow
-from the close callback (or any other window related callback).
-
-@par Old syntax
-@code
-int GLFWCALL window_close_callback(void);
-@endcode
-
-@par New syntax
-@code
-void window_close_callback(GLFWwindow* window);
-@endcode
-
-@note GLFW never clears the close flag to `GL_FALSE`, meaning you can use it
-for other reasons to close the window as well, for example the user choosing
-Quit from an in-game menu.
-
-
-@subsection moving_hints Persistent window hints
-
-The `glfwOpenWindowHint` function has been renamed to @ref glfwWindowHint.
-
-Window hints are no longer reset to their default values on window creation, but
-instead retain their values until modified by @ref glfwWindowHint or @ref
-glfwDefaultWindowHints, or until the library is terminated and re-initialized.
-
-
-@subsection moving_video_modes Video mode enumeration
-
-Video mode enumeration is now per-monitor.  The @ref glfwGetVideoModes function
-now returns all available modes for a specific monitor instead of requiring you
-to guess how large an array you need.  The `glfwGetDesktopMode` function, which
-had poorly defined behavior, has been replaced by @ref glfwGetVideoMode, which
-returns the current mode of a monitor.
-
-
-@subsection moving_char_up Removal of character actions
-
-The action parameter of the [character callback](@ref GLFWcharfun) has been
-removed.  This was an artefact of the origin of GLFW, i.e. being developed in
-English by a Swede.  However, many keyboard layouts require more than one key to
-produce characters with diacritical marks. Even the Swedish keyboard layout
-requires this for uncommon cases like ü.
-
-@par Old syntax
-@code
-void GLFWCALL character_callback(int character, int action);
-@endcode
-
-@par New syntax
-@code
-void character_callback(GLFWwindow* window, int character);
-@endcode
-
-
-@subsection moving_cursorpos Cursor position changes
-
-The `glfwGetMousePos` function has been renamed to @ref glfwGetCursorPos,
-`glfwSetMousePos` to @ref glfwSetCursorPos and `glfwSetMousePosCallback` to @ref
-glfwSetCursorPosCallback.
-
-The cursor position is now `double` instead of `int`, both for the direct
-functions and for the callback.  Some platforms can provide sub-pixel cursor
-movement and this data is now passed on to the application where available.  On
-platforms where this is not provided, the decimal part is zero.
-
-GLFW 3 only allows you to position the cursor within a window using @ref
-glfwSetCursorPos (formerly `glfwSetMousePos`) when that window is active.
-Unless the window is active, the function fails silently.
-
-
-@subsection moving_wheel Wheel position replaced by scroll offsets
-
-The `glfwGetMouseWheel` function has been removed.  Scrolling is the input of
-offsets and has no absolute position.  The mouse wheel callback has been
-replaced by a [scroll callback](@ref GLFWscrollfun) that receives
-two-dimensional floating point scroll offsets.  This allows you to receive
-precise scroll data from for example modern touchpads.
-
-@par Old syntax
-@code
-void GLFWCALL mouse_wheel_callback(int position);
-@endcode
-
-@par New syntax
-@code
-void scroll_callback(GLFWwindow* window, double xoffset, double yoffset);
-@endcode
-
-@par Removed functions
-`glfwGetMouseWheel`
-
-
-@subsection moving_repeat Key repeat action
-
-The `GLFW_KEY_REPEAT` enable has been removed and key repeat is always enabled
-for both keys and characters.  A new key action, `GLFW_REPEAT`, has been added
-to allow the [key callback](@ref GLFWkeyfun) to distinguish an initial key press
-from a repeat.  Note that @ref glfwGetKey still returns only `GLFW_PRESS` or
-`GLFW_RELEASE`.
-
-
-@subsection moving_keys Physical key input
-
-GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to
-the values generated by the current keyboard layout.  The tokens are named
-according to the values they would have using the standard US layout, but this
-is only a convenience, as most programmers are assumed to know that layout.
-This means that (for example) `GLFW_KEY_LEFT_BRACKET` is always a single key and
-is the same key in the same place regardless of what keyboard layouts the users
-of your program has.
-
-The key input facility was never meant for text input, although using it that
-way worked slightly better in GLFW 2.  If you were using it to input text, you
-should be using the character callback instead, on both GLFW 2 and 3.  This will
-give you the characters being input, as opposed to the keys being pressed.
-
-GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of
-having to remember whether to check for `'a'` or `'A'`, you now check for
-`GLFW_KEY_A`.
-
-
-@subsection moving_joystick Joystick function changes
-
-The `glfwGetJoystickPos` function has been renamed to @ref glfwGetJoystickAxes.
-
-The `glfwGetJoystickParam` function and the `GLFW_PRESENT`, `GLFW_AXES` and
-`GLFW_BUTTONS` tokens have been replaced by the @ref glfwJoystickPresent
-function as well as axis and button counts returned by the @ref
-glfwGetJoystickAxes and @ref glfwGetJoystickButtons functions.
-
-
-@subsection moving_mbcs Win32 MBCS support
-
-The Win32 port of GLFW 3 will not compile in
-[MBCS mode](http://msdn.microsoft.com/en-us/library/5z097dxa.aspx).
-However, because the use of the Unicode version of the Win32 API doesn't affect
-the process as a whole, but only those windows created using it, it's perfectly
-possible to call MBCS functions from other parts of the same application.
-Therefore, even if an application using GLFW has MBCS mode code, there's no need
-for GLFW itself to support it.
-
-
-@subsection moving_windows Support for versions of Windows older than XP
-
-All explicit support for version of Windows older than XP has been removed.
-There is no code that actively prevents GLFW 3 from running on these earlier
-versions, but it uses Win32 functions that those versions lack.
-
-Windows XP was released in 2001, and by now (January 2015) it has not only
-replaced almost all earlier versions of Windows, but is itself rapidly being
-replaced by Windows 7 and 8.  The MSDN library doesn't even provide
-documentation for version older than Windows 2000, making it difficult to
-maintain compatibility with these versions even if it was deemed worth the
-effort.
-
-The Win32 API has also not stood still, and GLFW 3 uses many functions only
-present on Windows XP or later.  Even supporting an OS as new as XP (new
-from the perspective of GLFW 2, which still supports Windows 95) requires
-runtime checking for a number of functions that are present only on modern
-version of Windows.
-
-
-@subsection moving_syskeys Capture of system-wide hotkeys
-
-The ability to disable and capture system-wide hotkeys like Alt+Tab has been
-removed.  Modern applications, whether they're games, scientific visualisations
-or something else, are nowadays expected to be good desktop citizens and allow
-these hotkeys to function even when running in full screen mode.
-
-
-@subsection moving_terminate Automatic termination
-
-GLFW 3 does not register @ref glfwTerminate with `atexit` at initialization,
-because `exit` calls registered functions from the calling thread and while it
-is permitted to call `exit` from any thread, @ref glfwTerminate may only be
-called from the main thread.
-
-To release all resources allocated by GLFW, you should call @ref glfwTerminate
-yourself, from the main thread, before the program terminates.  Note that this
-destroys all windows not already destroyed with @ref glfwDestroyWindow,
-invalidating any window handles you may still have.
-
-
-@subsection moving_glu GLU header inclusion
-
-GLFW 3 does not by default include the GLU header and GLU itself has been
-deprecated by [Khronos](https://en.wikipedia.org/wiki/Khronos_Group).  __New
-projects should avoid using GLU__, but if you need to compile legacy code that
-has been moved to GLFW 3, you can request that the GLFW header includes it by
-defining `GLFW_INCLUDE_GLU` before the inclusion of the GLFW header.
-
-@par Old syntax
-@code
-#include <GL/glfw.h>
-@endcode
-
-@par New syntax
-@code
-#define GLFW_INCLUDE_GLU
-#include <GLFW/glfw3.h>

-
-@section news_31 New features in 3.1
-
-These are the release highlights.  For a full list of changes see the
-[version history](http://www.glfw.org/changelog.html).
-
-
-@subsection news_31_cursor Custom mouse cursor images
-
-GLFW now supports creating and setting both custom cursor images and standard
-cursor shapes.  They are created with @ref glfwCreateCursor or @ref
-glfwCreateStandardCursor, set with @ref glfwSetCursor and destroyed with @ref
-glfwDestroyCursor.
-
-@see @ref cursor_object
-
-
-@subsection news_31_drop Path drop event
-
-GLFW now provides a callback for receiving the paths of files and directories
-dropped onto GLFW windows.  The callback is set with @ref glfwSetDropCallback.
-
-@see @ref path_drop
-
-
-@subsection news_31_emptyevent Main thread wake-up
-
-GLFW now provides the @ref glfwPostEmptyEvent function for posting an empty
-event from another thread to the main thread event queue, causing @ref
-glfwWaitEvents to return.
-
-@see @ref events
-
-
-@subsection news_31_framesize Window frame size query
-
-GLFW now supports querying the size, on each side, of the frame around the
-client area of a window, with @ref glfwGetWindowFrameSize.
-
-@see [Window size](@ref window_size)
-
-
-@subsection news_31_autoiconify Simultaneous multi-monitor rendering
-
-GLFW now supports disabling auto-iconification of full screen windows with
-the [GLFW_AUTO_ICONIFY](@ref window_hints_wnd) window hint.  This is intended
-for people building multi-monitor installations, where you need windows to stay
-in full screen despite losing input focus.
-
-
-@subsection news_31_floating Floating windows
-
-GLFW now supports floating windows, also called topmost or always on top, for
-easier debugging with the [GLFW_FLOATING](@ref window_hints_wnd) window hint.
-
-
-@subsection news_31_focused Initially unfocused windows
-
-GLFW now supports preventing a windowed mode window from gaining input focus on
-creation, with the [GLFW_FOCUSED](@ref window_hints_wnd) window hint.
-
-
-@subsection news_31_direct Direct access for window attributes and cursor position
-
-GLFW now queries the window input focus, visibility and iconification attributes
-and the cursor position directly instead of returning cached data.
-
-
-@subsection news_31_libovr Better interoperability with Oculus Rift
-
-GLFW now provides native access functions for the OS level handles corresponding
-to monitor objects, as well as a [brief guide](@ref rift).  It is also regularly
-tested for compatibility with the latest version of LibOVR (0.4.4 on release).
-
-
-@subsection news_31_charmods Character with modifiers callback
-
-GLFW now provides a callback for character events with modifier key bits.  The
-callback is set with @ref glfwSetCharModsCallback.  Unlike the regular character
-callback, this will report character events that will not result in a character
-being input, for example if the Control key is held down.
-
-@see @ref input_char
-
-
-@subsection news_31_single Single buffered framebuffers
-
-GLFW now supports the creation of single buffered windows, with the
-[GLFW_DOUBLEBUFFER](@ref window_hints_fb) window hint.
-
-
-@subsection news_31_glext Macro for including extension header
-
-GLFW now includes the extension header appropriate for the chosen OpenGL or
-OpenGL ES header when [GLFW_INCLUDE_GLEXT](@ref build_macros) is defined.  GLFW
-does not provide these headers.  They must be provided by your development
-environment or your OpenGL or OpenGL ES SDK.
-
-
-@subsection news_31_release Context release behaviors
-
-GLFW now supports controlling whether the pipeline is flushed when a context is
-made non-current, with the
-[GLFW_CONTEXT_RELEASE_BEHAVIOR](@ref window_hints_ctx) window hint, provided the
-machine supports the `GL_KHR_context_flush_control` extension.
-
-
-@subsection news_31_wayland (Experimental) Wayland support
-
-GLFW now has an _experimental_ Wayland display protocol backend that can be
-selected on Linux with a CMake option.
-
-
-@subsection news_31_mir (Experimental) Mir support
-
-GLFW now has an _experimental_ Mir display server backend that can be selected
-on Linux with a CMake option.
-
-
-@section news_30 New features in 3.0
-
-These are the release highlights.  For a full list of changes see the
-[version history](http://www.glfw.org/changelog.html).
-
-
-@subsection news_30_cmake CMake build system
-
-GLFW now uses the CMake build system instead of the various makefiles and
-project files used by earlier versions.  CMake is available for all platforms
-supported by GLFW, is present in most package systems and can generate
-makefiles and/or project files for most popular development environments.
-
-For more information on how to use CMake, see the
-[CMake manual](http://cmake.org/cmake/help/documentation.html).
-
-
-@subsection news_30_multiwnd Multi-window support
-
-GLFW now supports the creation of multiple windows, each with their own OpenGL
-or OpenGL ES context, and all window functions now take a window handle.  Event
-callbacks are now per-window and are provided with the handle of the window that
-received the event.  The @ref glfwMakeContextCurrent function has been added to
-select which context is current on a given thread.
-
-
-@subsection news_30_multimon Multi-monitor support
-
-GLFW now explicitly supports multiple monitors.  They can be enumerated with
-@ref glfwGetMonitors, queried with @ref glfwGetVideoModes, @ref
-glfwGetMonitorPos, @ref glfwGetMonitorName and @ref glfwGetMonitorPhysicalSize,
-and specified at window creation to make the newly created window full screen on
-that specific monitor.
-
-
-@subsection news_30_unicode Unicode support
-
-All string arguments to GLFW functions and all strings returned by GLFW now use
-the UTF-8 encoding.  This includes the window title, error string, clipboard
-text, monitor and joystick names as well as the extension function arguments (as
-ASCII is a subset of UTF-8).
-
-
-@subsection news_30_clipboard Clipboard text I/O
-
-GLFW now supports reading and writing plain text to and from the system
-clipboard, with the @ref glfwGetClipboardString and @ref glfwSetClipboardString
-functions.
-
-
-@subsection news_30_gamma Gamma ramp support
-
-GLFW now supports setting and reading back the gamma ramp of monitors, with the
-@ref glfwGetGammaRamp and @ref glfwSetGammaRamp functions.  There is also @ref
-glfwSetGamma, which generates a ramp from a gamma value and then sets it.
-
-
-@subsection news_30_gles OpenGL ES support
-
-GLFW now supports the creation of OpenGL ES contexts, by setting the
-`GLFW_CLIENT_API` window hint to `GLFW_OPENGL_ES_API`, where creation of such
-contexts are supported.  Note that GLFW _does not implement_ OpenGL ES, so your
-driver must provide support in a way usable by GLFW.  Modern Nvidia and Intel
-drivers support creation of OpenGL ES context using the GLX and WGL APIs, while
-AMD provides an EGL implementation instead.
-
-
-@subsection news_30_egl (Experimental) EGL support
-
-GLFW now has an experimental EGL context creation back end that can be selected
-through CMake options.
-
-
-@subsection news_30_hidpi High-DPI support
-
-GLFW now supports high-DPI monitors on both Windows and OS X, giving windows full
-resolution framebuffers where other UI elements are scaled up.  To achieve this,
-@ref glfwGetFramebufferSize and @ref glfwSetFramebufferSizeCallback have been
-added.  These work with pixels, while the rest of the GLFW API works with screen
-coordinates.  This is important as OpenGL uses pixels, not screen coordinates.
-
-
-@subsection news_30_error Error callback
-
-GLFW now has an error callback, which can provide your application with much
-more detailed diagnostics than was previously possible.  The callback is passed
-an error code and a description string.
-
-
-@subsection news_30_wndptr Per-window user pointer
-
-Each window now has a user-defined pointer, retrieved with @ref
-glfwGetWindowUserPointer and set with @ref glfwSetWindowUserPointer, to make it
-easier to integrate GLFW into C++ code.
-
-
-@subsection news_30_iconifyfun Window iconification callback
-
-Each window now has a callback for iconification and restoration events,
-which is set with @ref glfwSetWindowIconifyCallback.
-
-
-@subsection news_30_wndposfun Window position callback
-
-Each window now has a callback for position events, which is set with @ref
-glfwSetWindowPosCallback.
-
-
-@subsection news_30_wndpos Window position query
-
-The position of a window can now be retrieved using @ref glfwGetWindowPos.
-
-
-@subsection news_30_focusfun Window focus callback
-
-Each windows now has a callback for focus events, which is set with @ref
-glfwSetWindowFocusCallback.
-
-
-@subsection news_30_enterleave Cursor enter/leave callback
-
-Each window now has a callback for when the mouse cursor enters or leaves its
-client area, which is set with @ref glfwSetCursorEnterCallback.
-
-
-@subsection news_30_wndtitle Initial window title
-
-The title of a window is now specified at creation time, as one of the arguments
-to @ref glfwCreateWindow.
-
-
-@subsection news_30_hidden Hidden windows
-
-Windows can now be hidden with @ref glfwHideWindow, shown using @ref
-glfwShowWindow and created initially hidden with the `GLFW_VISIBLE` window hint.
-This allows for off-screen rendering in a way compatible with most drivers, as
-well as moving a window to a specific position before showing it.
-
-
-@subsection news_30_undecorated Undecorated windows
-
-Windowed mode windows can now be created without decorations, i.e. things like
-a frame, a title bar, with the `GLFW_DECORATED` window hint.  This allows for
-the creation of things like splash screens.
-
-
-@subsection news_30_keymods Modifier key bit masks
-
-[Modifier key bit mask](@ref mods) parameters have been added to the
-[mouse button](@ref GLFWmousebuttonfun) and [key](@ref GLFWkeyfun) callbacks.
-
-
-@subsection news_30_scancode Platform-specific scancodes
-
-A scancode parameter has been added to the [key callback](@ref GLFWkeyfun). Keys
-that don't have a [key token](@ref keys) still get passed on with the key
-parameter set to `GLFW_KEY_UNKNOWN`.  These scancodes will vary between machines
-and are intended to be used for key bindings.
-
-
-@subsection news_30_jsname Joystick names
-
-The name of a joystick can now be retrieved using @ref glfwGetJoystickName.

-/*!
-
-@page quick Getting started
-
-@tableofcontents
-
-This guide takes you through writing a simple application using GLFW 3.  The
-application will create a window and OpenGL context, render a rotating triangle
-and exit when the user closes the window or presses Escape.  This guide will
-introduce a few of the most commonly used functions, but there are many more.
-
-This guide assumes no experience with earlier versions of GLFW.  If you
-have used GLFW 2 in the past, read the @ref moving guide, as some functions
-behave differently in GLFW 3.
-
-
-@section quick_steps Step by step
-
-@subsection quick_include Including the GLFW header
-
-In the source files of your application where you use OpenGL or GLFW, you need
-to include the GLFW 3 header file.
-
-@code
-#include <GLFW/glfw3.h>
-@endcode
-
-This defines all the constants, types and function prototypes of the GLFW API.
-It also includes the OpenGL header, and defines all the constants and types
-necessary for it to work on your platform.
-
-For example, under Windows you are normally required to include `windows.h`
-before including `GL/gl.h`.  This would make your source file tied to Windows
-and pollute your code's namespace with the whole Win32 API.
-
-Instead, the GLFW header takes care of this for you, not by including
-`windows.h`, but rather by itself duplicating only the necessary parts of it.
-It does this only where needed, so if `windows.h` _is_ included, the GLFW header
-does not try to redefine those symbols.
-
-In other words:
-
-- Do _not_ include the OpenGL headers yourself, as GLFW does this for you
-- Do _not_ include `windows.h` or other platform-specific headers unless
-  you plan on using those APIs directly
-- If you _do_ need to include such headers, do it _before_ including the
-  GLFW one and it will detect this
-
-Starting with version 3.0, the GLU header `glu.h` is no longer included by
-default.  If you wish to include it, define `GLFW_INCLUDE_GLU` before the
-inclusion of the GLFW header.
-
-@code
-#define GLFW_INCLUDE_GLU
-#include <GLFW/glfw3.h>
-@endcode
-
-
-@subsection quick_init_term Initializing and terminating GLFW
-
-Before you can use most GLFW functions, the library must be initialized.  On
-successful initialization, `GL_TRUE` is returned.  If an error occurred,
-`GL_FALSE` is returned.
-
-@code
-if (!glfwInit())
-    exit(EXIT_FAILURE);
-@endcode
-
-When you are done using GLFW, typically just before the application exits, you
-need to terminate GLFW.
-
-@code
-glfwTerminate();
-@endcode
-
-This destroys any remaining windows and releases any other resources allocated by
-GLFW.  After this call, you must initialize GLFW again before using any GLFW
-functions that require it.
-
-
-@subsection quick_capture_error Setting an error callback
-
-Most events are reported through callbacks, whether it's a key being pressed,
-a GLFW window being moved, or an error occurring.  Callbacks are simply
-C functions (or C++ static methods) that are called by GLFW with arguments
-describing the event.
-
-In case a GLFW function fails, an error is reported to the GLFW error callback.
-You can receive these reports with an error callback.  This function must have
-the signature below.  This simple error callback just prints the error
-description to `stderr`.
-
-@code
-void error_callback(int error, const char* description)
-{
-    fputs(description, stderr);
-}
-@endcode
-
-Callback functions must be set, so GLFW knows to call them.  The function to set
-the error callback is one of the few GLFW functions that may be called before
-initialization, which lets you be notified of errors both during and after
-initialization.
-
-@code
-glfwSetErrorCallback(error_callback);
-@endcode
-
-
-@subsection quick_create_window Creating a window and context
-
-The window and its OpenGL context are created with a single call, which returns
-a handle to the created combined window and context object.  For example, this
-creates a 640 by 480 windowed mode window with an OpenGL context:
-
-@code
-GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
-@endcode
-
-If window or context creation fails, `NULL` will be returned, so it is necessary
-to check the return value.
-
-@code
-if (!window)
-{
-    glfwTerminate();
-    exit(EXIT_FAILURE);
-}
-@endcode
-
-The window handle is passed to all window related functions and is provided to
-along to all window related callbacks, so they can tell which window received
-the event.
-
-When a window is no longer needed, destroy it.
-
-@code
-glfwDestroyWindow(window);
-@endcode
-
-Once this function is called, no more events will be delivered for that window
-and its handle becomes invalid.
-
-
-@subsection quick_context_current Making the OpenGL context current
-
-Before you can use the OpenGL API, you must have a current OpenGL context.
-
-@code
-glfwMakeContextCurrent(window);
-@endcode
-
-The context will remain current until you make another context current or until
-the window owning the current context is destroyed.
-
-
-@subsection quick_window_close Checking the window close flag
-
-Each window has a flag indicating whether the window should be closed.
-
-When the user attempts to close the window, either by pressing the close widget
-in the title bar or using a key combination like Alt+F4, this flag is set to 1.
-Note that __the window isn't actually closed__, so you are expected to monitor
-this flag and either destroy the window or give some kind of feedback to the
-user.
-
-@code
-while (!glfwWindowShouldClose(window))
-{
-    // Keep running
-}
-@endcode
-
-You can be notified when the user is attempting to close the window by setting
-a close callback with @ref glfwSetWindowCloseCallback.  The callback will be
-called immediately after the close flag has been set.
-
-You can also set it yourself with @ref glfwSetWindowShouldClose.  This can be
-useful if you want to interpret other kinds of input as closing the window, like
-for example pressing the escape key.
-
-
-@subsection quick_key_input Receiving input events
-
-Each window has a large number of callbacks that can be set to receive all the
-various kinds of events.  To receive key press and release events, create a key
-callback function.
-
-@code
-static void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
-{
-    if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS)
-        glfwSetWindowShouldClose(window, GL_TRUE);
-}
-@endcode
-
-The key callback, like other window related callbacks, are set per-window.
-
-@code
-glfwSetKeyCallback(window, key_callback);
-@endcode
-
-In order for event callbacks to be called when events occur, you need to process
-events as described below.
-
-
-@subsection quick_render Rendering with OpenGL
-
-Once you have a current OpenGL context, you can use OpenGL normally.  In this
-tutorial, a multi-colored rotating triangle will be rendered.  The framebuffer
-size needs to be retrieved for `glViewport`.
-
-@code
-int width, height;
-glfwGetFramebufferSize(window, &width, &height);
-glViewport(0, 0, width, height);
-@endcode
-
-You can also set a framebuffer size callback using @ref
-glfwSetFramebufferSizeCallback and call `glViewport` from there.
-
-
-@subsection quick_timer Reading the timer
-
-To create smooth animation, a time source is needed.  GLFW provides a timer that
-returns the number of seconds since initialization.  The time source used is the
-most accurate on each platform and generally has micro- or nanosecond
-resolution.
-
-@code
-double time = glfwGetTime();
-@endcode
-
-
-@subsection quick_swap_buffers Swapping buffers
-
-GLFW windows by default use double buffering.  That means that each window has
-two rendering buffers; a front buffer and a back buffer.  The front buffer is
-the one being displayed and the back buffer the one you render to.
-
-When the entire frame has been rendered, the buffers need to be swapped with one
-another, so the back buffer becomes the front buffer and vice versa.
-
-@code
-glfwSwapBuffers(window);
-@endcode
-
-The swap interval indicates how many frames to wait until swapping the buffers,
-commonly known as _vsync_.  By default, the swap interval is zero, meaning
-buffer swapping will occur immediately.  On fast machines, many of those frames
-will never be seen, as the screen is still only updated typically 60-75 times
-per second, so this wastes a lot of CPU and GPU cycles.
-
-Also, because the buffers will be swapped in the middle the screen update,
-leading to [screen tearing](https://en.wikipedia.org/wiki/Screen_tearing).
-
-For these reasons, applications will typically want to set the swap interval to
-one.  It can be set to higher values, but this is usually not recommended,
-because of the input latency it leads to.
-
-@code
-glfwSwapInterval(1);
-@endcode
-
-This function acts on the current context and will fail unless a context is
-current.
-
-
-@subsection quick_process_events Processing events
-
-GLFW needs to communicate regularly with the window system both in order to
-receive events and to show that the application hasn't locked up.  Event
-processing must be done regularly while you have visible windows and is normally
-done each frame after buffer swapping.
-
-There are two methods for processing pending events; polling and waiting.  This
-example will use event polling, which processes only those events that have
-already been received and then returns immediately.  
-
-@code
-glfwPollEvents();
-@endcode
-
-This is the best choice when rendering continually, like most games do.  If
-instead you only need to update your rendering once you have received new input,
-@ref glfwWaitEvents is a better choice.  It waits until at least one event has
-been received, putting the thread to sleep in the meantime, and then processes
-all received events.  This saves a great deal of CPU cycles and is useful for,
-for example, many kinds of editing tools.
-
-
-@section quick_example Putting it together
-
-Now that you know how to initialize GLFW, create a window and poll for
-keyboard input, it's possible to create a simple program.
-
-@snippet simple.c code
-
-This program creates a 640 by 480 windowed mode window and starts a loop that
-clears the screen, renders a triangle and processes events until the user either
-presses Escape or closes the window.
-
-This program uses only a few of the many functions GLFW provides.  There are
-guides for each of the areas covered by GLFW.  Each guide will introduce all the
-functions for that category.
-
- - @ref intro
- - @ref window
- - @ref context
- - @ref monitor
- - @ref input
-
-
-@section quick_build Compiling and linking the program
-
-The complete program above can be found in the source distribution as
-`examples/simple.c` and is compiled along with all other examples when you
-build GLFW.  That is, if you have compiled GLFW then you have already built this
-as `simple.exe` on Windows, `simple` on Linux or `simple.app` on OS X.
-
-This tutorial ends here.  Once you have written a program that uses GLFW, you
-will need to compile and link it.  How to do that depends on the development
-environment you are using and is best explained by the documentation for that
-environment.  To learn about the details that are specific to GLFW, see
-@ref build.

-@page rift Oculus Rift guide
- 
-@tableofcontents
-
-This guide is intended to fill in the gaps between the
-[Oculus PC SDK documentation](https://developer.oculus.com/documentation/) and
-the rest of the GLFW documentation and is not a replacement for either.  It
-requires you to use [native access](@ref native) and assumes a certain level of
-proficiency with LibOVR, platform specific APIs and your chosen development
-environment.
-
-While GLFW has no explicit support for LibOVR, it is tested with and tries to
-interoperate well with it.
-
-@note Because of the speed of development of the Oculus SDK, this guide may
-become outdated before the next release.  If this is a local copy of the
-documentation, you may want to check the GLFW website for updates.  This
-revision of the guide is written against version 0.4.4 of the SDK.
-
-
-@section rift_include Including the LibOVR and GLFW header files
-
-Both the OpenGL LibOVR header and the GLFW native header need macros telling
-them what OS you are building for.  Because LibOVR only supports three major
-desktop platforms, this can be solved with canonical predefined macros.
-
-@code
-#if defined(_WIN32)
- #define GLFW_EXPOSE_NATIVE_WIN32
- #define GLFW_EXPOSE_NATIVE_WGL
- #define OVR_OS_WIN32
-#elif defined(__APPLE__)

- #define GLFW_EXPOSE_NATIVE_GLX
- #define OVR_OS_LINUX
-#endif
-
-#include <GLFW/glfw3.h>
-#include <GLFW/glfw3native.h>
-
-#include <OVR_CAPI_GL.h>
-@endcode
-
-Both the GLFW and LibOVR headers by default attempt to include the standard
-OpenGL `GL/gl.h` header (`OpenGL/gl.h` on OS X).  If you wish to use a different
-standard header or an [extension loading library](@ref context_glext_auto),
-include that header before these.
-
-
-@section rift_init Initializing LibOVR and GLFW
-
-LibOVR needs to be initialized before GLFW.  This means calling at least
-`ovr_Initialize`, `ovrHmd_Create` and `ovrHmd_ConfigureTracking` before @ref
-glfwInit.  Similarly, LibOVR must be shut down after GLFW.  This means calling
-`ovrHmd_Destroy` and `ovr_Shutdown` after @ref glfwTerminate.
-
-
-@section rift_direct Direct HMD mode
-
-Direct HMD mode is the recommended display mode for new applications, but the
-Oculus Rift runtime currently (January 2015) only supports this mode on Windows.
-In direct mode the HMD is not detectable as a GLFW monitor.
-
-
-@subsection rift_direct_create Creating a window and context
-
-If the HMD is in direct mode you can use either a full screen or a windowed mode
-window, but full screen is only recommended if there is a monitor that supports
-the resolution of the HMD.  Due to limitations in LibOVR, the size of the client
-area of the window must equal the resolution of the HMD.
-
-If the resolution of the HMD is much larger than the regular monitor, the window
-may be resized by the window manager on creation.  One way to avoid this is to
-make it undecorated with the [GLFW_DECORATED](@ref window_hints_wnd) window
-hint.
-
-
-@subsection rift_direct_attach Attaching the window to the HMD
-
-Once you have created the window and context, you need to attach the native
-handle of the GLFW window to the HMD.
-
-@code
-ovrHmd_AttachToWindow(hmd, glfwGetWin32Window(window), NULL, NULL);
-@endcode
-
-
-@section rift_extend Extend Desktop mode
-
-Extend desktop mode is a legacy display mode, but is still (January 2015) the
-only available mode on OS X and Linux, as well as on Windows machines that for
-technical reasons do not yet support direct HMD mode.
-
-
-@subsection rift_extend_detect Detecting a HMD with GLFW
-
-If the HMD is in extend desktop mode you can deduce which GLFW monitor it
-corresponds to and create a full screen window on that monitor.
-
-On Windows, the native display device name of a GLFW monitor corresponds to the
-display device name of the detected HMD as stored, in the `DisplayDeviceName`
-member of `ovrHmdDesc`.
-
-On OS X, the native display ID of a GLFW monitor corresponds to the display ID
-of the detected HMD, as stored in the `DisplayId` member of `ovrHmdDesc`.
-
-At the time of writing (January 2015), the Oculus SDK does not support detecting
-which monitor corresponds to the HMD in any sane fashion, but as long as the HMD
-is set up and rotated properly it can be found via the screen position and
-resolution provided by LibOVR.  This method may instead find another monitor
-that is mirroring the HMD, but this only matters if you intend to change its
-video mode.
-
-@code
-int i, count;
-GLFWmonitor** monitors = glfwGetMonitors(&count);
-
-for (i = 0;  i < count;  i++)
-{
-#if defined(_WIN32)
-    if (strcmp(glfwGetWin32Monitor(monitors[i]), hmd->DisplayDeviceName) == 0)
-        return monitors[i];
-#elif defined(__APPLE__)
-    if (glfwGetCocoaMonitor(monitors[i]) == hmd->DisplayId)
-        return monitors[i];
-#elif defined(__linux__)
-    int xpos, ypos;
-    const GLFWvidmode* mode = glfwGetVideoMode(monitors[i]);
-    glfwGetMonitorPos(monitors[i], &xpos, &ypos);
-

-        hmd->WindowsPos.y == ypos &&
-        hmd->Resolution.w == mode->width &&
-        hmd->Resolution.h == mode->height)
-    {
-        return monitors[i];
-    }
-#endif
-}
-@endcode
-
-
-@subsection rift_extend_create Creating a window and context
-
-The window is created as a regular full screen window on the found monitor.  It
-is usually a good idea to create a
-[windowed full screen](@ref window_windowed_full_screen) window, as the HMD will
-very likely already be set to the correct video mode.  However, in extend
-desktop mode it behaves like a regular monitor and any supported video mode can
-be requested.
-
-If other monitors are mirroring the HMD and you request a different video mode,
-all monitors in the mirroring set will get the new video mode.
-
-
-@section rift_render Rendering to the HMD
-
-@subsection rift_render_sdk SDK distortion rendering
-
-If you wish to use SDK distortion rendering you will need some information from
-GLFW to configure the renderer.  Below are the parts of the `ovrGLConfig` union
-that need to be filled with from GLFW.  Note that there are other fields that
-also need to be filled for `ovrHmd_ConfigureRendering` to succeed.
-
-Before configuring SDK distortion rendering you should make your context
-current.
-
-@code
-    int width, height;
-    union ovrGLConfig config;
-
-    glfwGetFramebufferSize(window, &width, &height);
-
-    config.OGL.Header.BackBufferSize.w = width;
-    config.OGL.Header.BackBufferSize.h = height;
-#if defined(_WIN32)
-    config.OGL.Window = glfwGetWin32Window(window);
-#elif defined(__APPLE__)
-#elif defined(__linux__)
-    config.OGL.Disp = glfwGetX11Display();
-#endif
-@endcode
-
-When using SDK distortion rendering you should not swap the buffers yourself, as
-the HMD is updated by `ovrHmd_EndFrame`.
-
-
-@subsection rift_render_custom Client distortion rendering
-
-With client distortion rendering you are in full control of the contents of the
-HMD and should render and swap the buffers normally.

-@page window Window guide
- 
-@tableofcontents
-
-This guide introduces the window related functions of GLFW.  There are also
-guides for the other areas of GLFW.
-
- - @ref intro
- - @ref context
- - @ref monitor
- - @ref input
-
-
-@section window_object Window objects
-
-The @ref GLFWwindow object encapsulates both a window and a context.  They are
-created with @ref glfwCreateWindow and destroyed with @ref glfwDestroyWindow, or
-@ref glfwTerminate, if any remain.  As the window and context are inseparably
-linked, the object pointer is used as both a context and window handle.
-
-To see the event stream provided to the various window related callbacks, run
-the `events` test program.
-
-
-@subsection window_creation Window creation
-
-A window and its OpenGL or OpenGL ES context are created with @ref
-glfwCreateWindow, which returns a handle to the created window object.  For
-example, this creates a 640 by 480 windowed mode window:
-
-@code
-GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
-@endcode
-
-If window creation fails, `NULL` will be returned, so it is necessary to check
-the return value.
-
-The window handle is passed to all window related functions and is provided to
-along with all input events, so event handlers can tell which window received
-the event.
-
-
-@subsubsection window_full_screen Full screen windows
-
-To create a full screen window, you need to specify which monitor the window
-should use.  In most cases, the user's primary monitor is a good choice.
-For more information about retrieving monitors, see @ref monitor_monitors. 
-
-@code
-GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", glfwGetPrimaryMonitor(), NULL);
-@endcode
-
-Full screen windows cover the entire display area of a monitor, have no border
-or decorations.
-
-Each field of the @ref GLFWvidmode structure corresponds to a function parameter
-or window hint and combine to form the _desired video mode_ for that window.
-The supported video mode most closely matching the desired video mode will be
-set for the chosen monitor as long as the window has input focus.  For more
-information about retrieving video modes, see @ref monitor_modes.
-
-Video mode field        | Corresponds to
------------------------ | ------------------------
-GLFWvidmode.width       | `width` parameter
-GLFWvidmode.height      | `height` parameter
-GLFWvidmode.redBits     | `GLFW_RED_BITS` hint
-GLFWvidmode.greenBits   | `GLFW_GREEN_BITS` hint
-GLFWvidmode.blueBits    | `GLFW_BLUE_BITS` hint
-GLFWvidmode.refreshRate | `GLFW_REFRESH_RATE` hint
-
-Once you have a full screen window, you can change its resolution with @ref
-glfwSetWindowSize.  The new video mode will be selected and set the same way as
-the video mode chosen by @ref glfwCreateWindow.
-
-By default, the original video mode of the monitor will be restored and the
-window iconified if it loses input focus, to allow the user to switch back to
-the desktop.  This behavior can be disabled with the `GLFW_AUTO_ICONIFY` window
-hint, for example if you wish to simultaneously cover multiple windows with full
-screen windows.
-
-
-@subsubsection window_windowed_full_screen "Windowed full screen" windows
-
-To create a so called _windowed full screen_ or _borderless full screen_ window,
-i.e. a full screen window that doesn't change the video mode of the monitor, you
-need to request the current video mode of the chosen monitor.
-
-@code
-const GLFWvidmode* mode = glfwGetVideoMode(monitor);
-
-glfwWindowHint(GLFW_RED_BITS, mode->redBits);
-glfwWindowHint(GLFW_GREEN_BITS, mode->greenBits);
-glfwWindowHint(GLFW_BLUE_BITS, mode->blueBits);
-glfwWindowHint(GLFW_REFRESH_RATE, mode->refreshRate);
-
-GLFWwindow* window = glfwCreateWindow(mode->width, mode->height, "My Title", monitor, NULL);
-@endcode
-
-GLFW will detect this and will not perform any mode setting for that window.   
-
-
-@subsection window_destruction Window destruction
-
-When a window is no longer needed, destroy it with @ref glfwDestroyWindow.
-
-@code
-glfwDestroyWindow(window);
-@endcode
-
-Window destruction always succeeds.  Before the actual destruction, all
-callbacks are removed so no further events will be delivered for the window.
-All windows remaining when @ref glfwTerminate is called are destroyed as well.
-
-When a full screen window is destroyed, the original video mode of its monitor
-is restored, but the gamma ramp is left untouched.
-
-
-@subsection window_hints Window creation hints
-
-There are a number of hints that can be set before the creation of a window and
-context.  Some affect the window itself, others affect the framebuffer or
-context.  These hints are set to their default values each time the library is
-initialized with @ref glfwInit, can be set individually with @ref glfwWindowHint
-and reset all at once to their defaults with @ref glfwDefaultWindowHints.
-
-Note that hints need to be set _before_ the creation of the window and context
-you wish to have the specified attributes.
-
-
-@subsubsection window_hints_hard Hard and soft constraints
-
-Some window hints are hard constraints.  These must match the available
-capabilities _exactly_ for window and context creation to succeed.  Hints
-that are not hard constraints are matched as closely as possible, but the
-resulting window and context may differ from what these hints requested.  To
-find out the actual attributes of the created window and context, use the
-@ref glfwGetWindowAttrib function.
-
-The following hints are always hard constraints:
-- `GLFW_STEREO`
-- `GLFW_DOUBLEBUFFER`
-- `GLFW_CLIENT_API`
-
-The following additional hints are hard constraints when requesting an OpenGL
-context, but are ignored when requesting an OpenGL ES context:
-- `GLFW_OPENGL_FORWARD_COMPAT`
-- `GLFW_OPENGL_PROFILE`
-
-
-@subsubsection window_hints_wnd Window related hints
-
-`GLFW_RESIZABLE` specifies whether the (windowed mode) window will be resizable
-_by the user_.  The window will still be resizable using the @ref
-glfwSetWindowSize function.  This hint is ignored for full screen windows.
-
-`GLFW_VISIBLE` specifies whether the (windowed mode) window will be initially
-visible.  This hint is ignored for full screen windows.
-
-`GLFW_DECORATED` specifies whether the (windowed mode) window will have window
-decorations such as a border, a close widget, etc.  This hint is ignored for
-full screen windows.  Note that even though a window may lack a close widget, it
-is usually still possible for the user to generate close events.
-
-`GLFW_FOCUSED` specifies whether the (windowed mode) window will be given input
-focus when created.  This hint is ignored for full screen and initially hidden
-windows.
-
-`GLFW_AUTO_ICONIFY` specifies whether the (full screen) window will
-automatically iconify and restore the previous video mode on input focus loss.
-This hint is ignored for windowed mode windows.
-
-`GLFW_FLOATING` specifies whether the window will be floating above other
-regular windows, also called topmost or always-on-top.  This is intended
-primarily for debugging purposes and cannot be used to implement proper full
-screen windows.  This hint is ignored for full screen windows.
-
-
-@subsubsection window_hints_fb Framebuffer related hints
-
-`GLFW_RED_BITS`, `GLFW_GREEN_BITS`, `GLFW_BLUE_BITS`, `GLFW_ALPHA_BITS`,
-`GLFW_DEPTH_BITS` and `GLFW_STENCIL_BITS` specify the desired bit depths of the
-various components of the default framebuffer.  `GLFW_DONT_CARE` means the
-application has no preference.
-
-`GLFW_ACCUM_RED_BITS`, `GLFW_ACCUM_GREEN_BITS`, `GLFW_ACCUM_BLUE_BITS` and
-`GLFW_ACCUM_ALPHA_BITS` specify the desired bit depths of the various components
-of the accumulation buffer.  `GLFW_DONT_CARE` means the application has no
-preference.
-
-@par
-Accumulation buffers are a legacy OpenGL feature and should not be used in new
-code.
-
-`GLFW_AUX_BUFFERS` specifies the desired number of auxiliary buffers.
-`GLFW_DONT_CARE` means the application has no preference.
-
-@par
-Auxiliary buffers are a legacy OpenGL feature and should not be used in new
-code.
-
-`GLFW_STEREO` specifies whether to use stereoscopic rendering.  This is a hard
-constraint.
-
-`GLFW_SAMPLES` specifies the desired number of samples to use for multisampling.
-Zero disables multisampling.  `GLFW_DONT_CARE` means the application has no
-preference.
-
-`GLFW_SRGB_CAPABLE` specifies whether the framebuffer should be sRGB capable.
-
-`GLFW_DOUBLEBUFFER` specifies whether the framebuffer should be double buffered.
-You nearly always want to use double buffering.  This is a hard constraint.
-
-
-@subsubsection window_hints_mtr Monitor related hints
-
-`GLFW_REFRESH_RATE` specifies the desired refresh rate for full screen windows.
-If set to `GLFW_DONT_CARE`, the highest available refresh rate will be used.
-This hint is ignored for windowed mode windows.
-
-
-@subsubsection window_hints_ctx Context related hints
-
-`GLFW_CLIENT_API` specifies which client API to create the context for.
-Possible values are `GLFW_OPENGL_API` and `GLFW_OPENGL_ES_API`.  This is a hard
-constraint.
-
-`GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR` specify the client
-API version that the created context must be compatible with.  The exact
-behavior of these hints depend on the requested client API.
-
-@par
-__OpenGL:__ `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR` are not hard
-constraints, but creation will fail if the OpenGL version of the created context
-is less than the one requested.  It is therefore perfectly safe to use the
-default of version 1.0 for legacy code and you may still get
-backwards-compatible contexts of version 3.0 and above when available.
-
-@par
-While there is no way to ask the driver for a context of the highest supported
-version, GLFW will attempt to provide this when you ask for a version 1.0
-context, which is the default for these hints.
-
-@par
-__OpenGL ES:__ `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR` are not hard
-constraints, but creation will fail if the OpenGL ES version of the created
-context is less than the one requested.  Additionally, OpenGL ES 1.x cannot be
-returned if 2.0 or later was requested, and vice versa.  This is because OpenGL
-ES 3.x is backward compatible with 2.0, but OpenGL ES 2.0 is not backward
-compatible with 1.x.
-
-`GLFW_OPENGL_FORWARD_COMPAT` specifies whether the OpenGL context should be
-forward-compatible, i.e. one where all functionality deprecated in the requested
-version of OpenGL is removed.  This may only be used if the requested OpenGL
-version is 3.0 or above.  If OpenGL ES is requested, this hint is ignored.
-
-@par
-Forward-compatibility is described in detail in the
-[OpenGL Reference Manual](https://www.opengl.org/registry/).
-
-`GLFW_OPENGL_DEBUG_CONTEXT` specifies whether to create a debug OpenGL context,
-which may have additional error and performance issue reporting functionality.
-If OpenGL ES is requested, this hint is ignored.
-
-`GLFW_OPENGL_PROFILE` specifies which OpenGL profile to create the context for.
-Possible values are one of `GLFW_OPENGL_CORE_PROFILE` or
-`GLFW_OPENGL_COMPAT_PROFILE`, or `GLFW_OPENGL_ANY_PROFILE` to not request
-a specific profile.  If requesting an OpenGL version below 3.2,
-`GLFW_OPENGL_ANY_PROFILE` must be used.  If another OpenGL ES is requested,
-this hint is ignored.
-
-@par
-OpenGL profiles are described in detail in the
-[OpenGL Reference Manual](https://www.opengl.org/registry/).
-
-`GLFW_CONTEXT_ROBUSTNESS` specifies the robustness strategy to be used by the
-context.  This can be one of `GLFW_NO_RESET_NOTIFICATION` or
-`GLFW_LOSE_CONTEXT_ON_RESET`, or `GLFW_NO_ROBUSTNESS` to not request
-a robustness strategy.
-
-`GLFW_CONTEXT_RELEASE_BEHAVIOR` specifies the release behavior to be
-used by the context.  Possible values are one of `GLFW_ANY_RELEASE_BEHAVIOR`,
-`GLFW_RELEASE_BEHAVIOR_FLUSH` or `GLFW_RELEASE_BEHAVIOR_NONE`.  If the
-behavior is `GLFW_ANY_RELEASE_BEHAVIOR`, the default behavior of the context
-creation API will be used.  If the behavior is `GLFW_RELEASE_BEHAVIOR_FLUSH`,
-the pipeline will be flushed whenever the context is released from being the
-current one.  If the behavior is `GLFW_RELEASE_BEHAVIOR_NONE`, the pipeline will
-not be flushed on release.
-
-@par
-Context release behaviors are described in detail by the
-[GL_KHR_context_flush_control](https://www.opengl.org/registry/specs/KHR/context_flush_control.txt)
-extension.

-@section window_events Window event processing
-
-See @ref events.
-
-
-@section window_properties Window properties and events
-
-@subsection window_userptr User pointer
-
-Each window has a user pointer that can be set with @ref
-glfwSetWindowUserPointer and fetched with @ref glfwGetWindowUserPointer.  This
-can be used for any purpose you need and will not be modified by GLFW throughout
-the life-time of the window.
-
-The initial value of the pointer is `NULL`.
-
-
-@subsection window_close Window closing and close flag
-
-When the user attempts to close the window, for example by clicking the close
-widget or using a key chord like Alt+F4, the _close flag_ of the window is set.
-The window is however not actually destroyed and, unless you watch for this
-state change, nothing further happens.
-
-The current state of the close flag is returned by @ref glfwWindowShouldClose
-and can be set or cleared directly with @ref glfwSetWindowShouldClose.  A common
-pattern is to use the close flag as a main loop condition.
-
-@code
-while (!glfwWindowShouldClose(window))
-{
-    render(window);
-
-    glfwSwapBuffers(window);
-    glfwPollEvents();
-}
-@endcode
-
-If you wish to be notified when the user attempts to close a window, set a close
-callback.
-
-@code
-glfwSetWindowCloseCallback(window, window_close_callback);
-@endcode
-
-The callback function is called directly _after_ the close flag has been set.
-It can be used for example to filter close requests and clear the close flag
-again unless certain conditions are met.
-
-@code
-void window_close_callback(GLFWwindow* window)
-{
-    if (!time_to_close)
-        glfwSetWindowShouldClose(window, GL_FALSE);
-}
-@endcode
-
-
-@subsection window_size Window size
-
-The size of a window can be changed with @ref glfwSetWindowSize.  For windowed
-mode windows, this sets the size, in
-[screen coordinates](@ref coordinate_systems) of the _client area_ or _content
-area_ of the window.  The window system may impose limits on window size.
-
-@code
-glfwSetWindowSize(window, 640, 480);
-@endcode
-
-For full screen windows, the specified size becomes the new resolution of the
-window's *desired video mode*.  The video mode most closely matching the new
-desired video mode is set immediately.  The window is resized to fit the
-resolution of the set video mode.
-
-If you wish to be notified when a window is resized, whether by the user or
-the system, set a size callback.
-
-@code
-glfwSetWindowSizeCallback(window, window_size_callback);
-@endcode
-
-The callback function receives the new size, in screen coordinates, of the
-client area of the window when it is resized.
-
-@code
-void window_size_callback(GLFWwindow* window, int width, int height)
-{
-}
-@endcode
-
-There is also @ref glfwGetWindowSize for directly retrieving the current size of
-a window.
-
-@code
-int width, height;
-glfwGetWindowSize(window, &width, &height);
-@endcode
-
-@note Do not pass the window size to `glViewport` or other pixel-based OpenGL
-calls.  The window size is in screen coordinates, not pixels.  Use the
-[framebuffer size](@ref window_fbsize), which is in pixels, for pixel-based
-calls.
-
-The above functions work with the size of the client area, but decorated windows
-typically have title bars and window frames around this rectangle.  You can
-retrieve the extents of these with @ref glfwGetWindowFrameSize.
-
-@code
-int left, top, right, bottom;
-glfwGetWindowFrameSize(window, &left, &top, &right, &bottom);
-@endcode
-
-The returned values are the distances, in screen coordinates, from the edges of
-the client area to the corresponding edges of the full window.  As they are
-distances and not coordinates, they are always zero or positive.
-
-
-@subsection window_fbsize Framebuffer size
-
-While the size of a window is measured in screen coordinates, OpenGL works with
-pixels.  The size you pass into `glViewport`, for example, should be in pixels.
-On some machines screen coordinates and pixels are the same, but on others they
-will not be.  There is a second set of functions to retrieve the size, in
-pixels, of the framebuffer of a window.
-
-If you wish to be notified when the framebuffer of a window is resized, whether
-by the user or the system, set a size callback.
-
-@code
-glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
-@endcode
-
-The callback function receives the new size of the framebuffer when it is
-resized, which can for example be used to update the OpenGL viewport.
-
-@code
-void framebuffer_size_callback(GLFWwindow* window, int width, int height)
-{
-    glViewport(0, 0, width, height);
-}
-@endcode
-
-There is also @ref glfwGetFramebufferSize for directly retrieving the current
-size of the framebuffer of a window.
-
-@code
-int width, height;
-glfwGetFramebufferSize(window, &width, &height);
-glViewport(0, 0, width, height);
-@endcode
-
-The size of a framebuffer may change independently of the size of a window, for
-example if the window is dragged between a regular monitor and a high-DPI one.
-
-
-@subsection window_pos Window position
-
-The position of a windowed-mode window can be changed with @ref
-glfwSetWindowPos.  This moves the window so that the upper-left corner of its
-client area has the specified [screen coordinates](@ref coordinate_systems).
-The window system may put limitations on window placement.
-
-@code
-glfwSetWindowPos(window, 100, 100);
-@endcode
-
-If you wish to be notified when a window is moved, whether by the user, system
-or your own code, set a position callback.
-
-@code
-glfwSetWindowPosCallback(window, window_pos_callback);
-@endcode
-
-The callback function receives the new position of the upper-left corner of the 
-client area when the window is moved.
-
-@code
-void window_pos_callback(GLFWwindow* window, int xpos, int ypos)
-{
-}
-@endcode
-
-There is also @ref glfwGetWindowPos for directly retrieving the current position
-of the client area of the window.
-
-@code
-int xpos, ypos;
-glfwGetWindowPos(window, &xpos, &ypos);
-@endcode
-
-
-@subsection window_title Window title
-
-All GLFW windows have a title, although undecorated or full screen windows may
-not display it or only display it in a task bar or similar interface.  You can
-set a UTF-8 encoded window title with @ref glfwSetWindowTitle.
-
-@code
-glfwSetWindowTitle(window, "My Window");
-@endcode
-
-The specified string is copied before the function returns, so there is no need
-to keep it around.
-
-As long as your source file is encoded as UTF-8, you can use any Unicode
-characters directly in the source.
-
-@code
-glfwSetWindowTitle(window, "ヒカルの碁");
-@endcode
-
-
-@subsection window_monitor Window monitor
-
-Full screen windows are associated with a specific monitor.  You can get the
-handle for this monitor with @ref glfwGetWindowMonitor.
-
-@code
-GLFWmonitor* monitor = glfwGetWindowMonitor(window);
-@endcode
-
-This monitor handle is one of those returned by @ref glfwGetMonitors.
-
-For windowed mode windows, this function returns `NULL`.  This is the
-recommended way to tell full screen windows from windowed mode windows.
-
-
-@subsection window_iconify Window iconification
-
-Windows can be iconified (i.e. minimized) with @ref glfwIconifyWindow.
-
-@code
-glfwIconifyWindow(window);
-@endcode
-
-When a full screen window is iconified, the original video mode of its monitor
-is restored until the user or application restores the window.
-
-Iconified windows can be restored with @ref glfwRestoreWindow.
-
-@code
-glfwRestoreWindow(window);
-@endcode
-
-When a full screen window is restored, the desired video mode is restored to its
-monitor as well.
-
-If you wish to be notified when a window is iconified or restored, whether by
-the user, system or your own code, set a iconify callback.
-
-@code
-glfwSetWindowIconifyCallback(window, window_iconify_callback);
-@endcode
-
-The callback function receives changes in the iconification state of the window.
-
-@code
-void window_iconify_callback(GLFWwindow* window, int iconified)
-{
-    if (iconified)
-    {
-        // The window was iconified
-    }
-    else
-    {
-        // The window was restored
-    }
-}
-@endcode
-
-You can also get the current iconification state with @ref glfwGetWindowAttrib.
-
-@code
-int iconified = glfwGetWindowAttrib(window, GLFW_ICONIFIED);
-@endcode
-
-
-@subsection window_hide Window visibility
-
-Windowed mode windows can be hidden with @ref glfwHideWindow.
-
-@code
-glfwHideWindow(window);
-@endcode
-
-This makes the window completely invisible to the user, including removing it
-from the task bar, dock or window list.  Full screen windows cannot be hidden
-and calling @ref glfwHideWindow on a full screen window does nothing.
-
-Hidden windows can be shown with @ref glfwShowWindow.
-
-@code
-glfwShowWindow(window);
-@endcode
-
-Windowed mode windows can be created initially hidden with the `GLFW_VISIBLE`
-[window hint](@ref window_hints_wnd).  Windows created hidden are completely
-invisible to the user until shown.  This can be useful if you need to set up
-your window further before showing it, for example moving it to a specific
-location.
-
-You can also get the current visibility state with @ref glfwGetWindowAttrib.
-
-@code
-int visible = glfwGetWindowAttrib(window, GLFW_VISIBLE);
-@endcode
-
-
-@subsection window_focus Window input focus
-
-If you wish to be notified when a window gains or loses input focus, whether by
-the user, system or your own code, set a focus callback.
-
-@code
-glfwSetWindowFocusCallback(window, window_focus_callback);
-@endcode
-
-The callback function receives changes in the input focus state of the window.
-
-@code
-void window_focus_callback(GLFWwindow* window, int focused)
-{
-    if (focused)
-    {
-        // The window gained input focus
-    }
-    else
-    {
-        // The window lost input focus
-    }
-}
-@endcode
-
-You can also get the current input focus state with @ref glfwGetWindowAttrib.
-
-@code
-int focused = glfwGetWindowAttrib(window, GLFW_FOCUSED);
-@endcode
-
-
-@subsection window_refresh Window damage and refresh
-
-If you wish to be notified when the contents of a window is damaged and needs
-to be refreshed, set a window refresh callback.
-
-@code
-glfwSetWindowRefreshCallback(m_handle, window_refresh_callback);
-@endcode
-
-The callback function is called when the contents of the window needs to be
-refreshed.
-
-@code
-void window_refresh_callback(GLFWwindow* window)
-{
-    draw_editor_ui(window);
-    glfwSwapBuffers(window);
-}
-@endcode
-
-@note On compositing window systems such as Aero, Compiz or Aqua, where the
-window contents are saved off-screen, this callback might only be called when
-the window or framebuffer is resized.
-
-
-@subsection window_attribs Window attributes
-
-Windows have a number of attributes that can be returned using @ref
-glfwGetWindowAttrib.  Some reflect state that may change during the lifetime of
-the window, while others reflect the corresponding hints and are fixed at the
-time of creation.  Some are related to the actual window and others to its
-context.
-
-@code
-if (glfwGetWindowAttrib(window, GLFW_FOCUSED))
-{
-    // window has input focus
-}
-@endcode
-
-
-@subsubsection window_attribs_wnd Window related attributes
-
-`GLFW_FOCUSED` indicates whether the specified window has input focus.  Initial
-input focus is controlled by the [window hint](@ref window_hints_wnd) with the
-same name.   
-
-`GLFW_ICONIFIED` indicates whether the specified window is iconified, whether by
-the user or with @ref glfwIconifyWindow.
-
-`GLFW_VISIBLE` indicates whether the specified window is visible.  Window
-visibility can be controlled with @ref glfwShowWindow and @ref glfwHideWindow
-and initial visibility is controlled by the [window hint](@ref window_hints_wnd)
-with the same name.  
-
-`GLFW_RESIZABLE` indicates whether the specified window is resizable _by the
-user_.  This is set on creation with the [window hint](@ref window_hints_wnd)
-  with the same name.
-
-`GLFW_DECORATED` indicates whether the specified window has decorations such as
-a border, a close widget, etc.  This is set on creation with the
-[window hint](@ref window_hints_wnd) with the same name. 
-
-`GLFW_FLOATING` indicates whether the specified window is floating, also called
-topmost or always-on-top.  This is controlled by the
-[window hint](@ref window_hints_wnd) with the same name. 
-
-
-@subsubsection window_attribs_ctx Context related attributes
-
-`GLFW_CLIENT_API` indicates the client API provided by the window's context;
-either `GLFW_OPENGL_API` or `GLFW_OPENGL_ES_API`.
-
-`GLFW_CONTEXT_VERSION_MAJOR`, `GLFW_CONTEXT_VERSION_MINOR` and
-`GLFW_CONTEXT_REVISION` indicate the client API version of the window's context.
-
-`GLFW_OPENGL_FORWARD_COMPAT` is `GL_TRUE` if the window's context is an OpenGL
-forward-compatible one, or `GL_FALSE` otherwise.
-
-`GLFW_OPENGL_DEBUG_CONTEXT` is `GL_TRUE` if the window's context is an OpenGL
-debug context, or `GL_FALSE` otherwise.
-
-`GLFW_OPENGL_PROFILE` indicates the OpenGL profile used by the context.  This is
-`GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE` if the context uses
-a known profile, or `GLFW_OPENGL_ANY_PROFILE` if the OpenGL profile is unknown
-or the context is an OpenGL ES context.  Note that the returned profile may not
-match the profile bits of the context flags, as GLFW will try other means of
-detecting the profile when no bits are set.
-
-`GLFW_CONTEXT_ROBUSTNESS` indicates the robustness strategy used by the context.
-This is `GLFW_LOSE_CONTEXT_ON_RESET` or `GLFW_NO_RESET_NOTIFICATION` if the
-window's context supports robustness, or `GLFW_NO_ROBUSTNESS` otherwise.
-
-
-@section buffer_swap Buffer swapping
-
-GLFW windows are by default double buffered.  That means that you have two
-rendering buffers; a front buffer and a back buffer.  The front buffer is
-the one being displayed and the back buffer the one you render to.
-
-When the entire frame has been rendered, it is time to swap the back and the
-front buffers in order to display what has been rendered and begin rendering
-a new frame.  This is done with @ref glfwSwapBuffers.
-
-@code
-glfwSwapBuffers(window);
-@endcode
-
-Sometimes it can be useful to select when the buffer swap will occur.  With the
-function @ref glfwSwapInterval it is possible to select the minimum number of
-monitor refreshes the driver wait should from the time @ref glfwSwapBuffers was
-called before swapping the buffers:
-
-@code
-glfwSwapInterval(1);
-@endcode
-
-If the interval is zero, the swap will take place immediately when @ref
-glfwSwapBuffers is called without waiting for a refresh.  Otherwise at least
-interval retraces will pass between each buffer swap.  Using a swap interval of
-zero can be useful for benchmarking purposes, when it is not desirable to
-measure the time it takes to wait for the vertical retrace.  However, a swap
-interval of one lets you avoid tearing.
-
-Note that this may not work on all machines, as some drivers have
-user-controlled settings that override any swap interval the application
-requests.  It is also by default disabled on Windows Vista and later when using
-DWM (Aero), as using it there sometimes leads to severe jitter.  You can
-forcibly enable it for machines using DWM using @ref compile_options_win32.

- * Title:   GLBoing
- * Desc:    Tribute to Amiga Boing.
- * Author:  Jim Brooks  <gfx@jimbrooks.org>
- *          Original Amiga authors were R.J. Mical and Dale Luck.
- *          GLFW conversion by Marcus Geelnard
- * Notes:   - 360' = 2*PI [radian]
- *
- *          - Distances between objects are created by doing a relative
- *            Z translations.
- *
- *          - Although OpenGL enticingly supports alpha-blending,
- *            the shadow of the original Boing didn't affect the color
- *            of the grid.
- *
- *          - [Marcus] Changed timing scheme from interval driven to frame-
- *            time based animation steps (which results in much smoother
- *            movement)
- *
- * History of Amiga Boing:
- *
- * Boing was demonstrated on the prototype Amiga (codenamed "Lorraine") in
- * 1985. According to legend, it was written ad-hoc in one night by
- * R. J. Mical and Dale Luck. Because the bouncing ball animation was so fast
- * and smooth, attendees did not believe the Amiga prototype was really doing
- * the rendering. Suspecting a trick, they began looking around the booth for
- * a hidden computer or VCR.

+
+NanoGUI is a a minimalistic cross-platform widget library for OpenGL 3.x.
+It supports automatic layout generation, stateful C++11 lambdas callbacks,
+a variety of useful widget types and Retina-capable rendering on Apple devices
+thanks to [NanoVG](https://github.com/memononen/NanoVG) by Mikko Mononen.
+Python bindings of all functionality are provided using
+[pybind11](https://github.com/wjakob/pybind11).

+
+## Description
+NanoGUI builds on [GLFW](http://www.glfw.org/) for cross-platform OpenGL context
+creation and event handling, [GLEW](http://glew.sourceforge.net/) to use OpenGL
+3.x Windows, [Eigen](http://eigen.tuxfamily.org/index.php?title=Main_Page) for
+basic vector types, and [NanoVG](https://github.com/memononen/NanoVG) to draw
+2D primitives.
+
+Note that the depencency library NanoVG already includes some basic example
+code to draw good-looking static widgets; what NanoGUI does is to flesh it
+out into a complete GUI toolkit with event handling, layout generation, etc.
+
+NanoGUI currently works on Mac OS X (Clang) Linux (GCC or Clang) and Windows
+(Visual Studio ≥ 2015); it requires a recent C++11 capable compiler. All
+dependencies are jointly built using a CMake-based build system.
+
+## Creating widgets
+NanoGUI makes it easy to instantiate widgets, set layout constraints, and
+register event callbacks using high-level C++11 code. For instance, the
+following two lines from the included example application add a new button to
+an existing window `window` and register an event callback.
+```C++
+Button *b = new Button(window, "Plain button");
+b->setCallback([] { cout << "pushed!" << endl; });
+```
+
+The following lines from the example application create the coupled
+slider and text box on the bottom of the second window (see the screenshot).
+```C++
+/* Create an empty panel with a horizontal layout */
+Widget *panel = new Widget(window);
+panel->setLayout(new BoxLayout(BoxLayout::Horizontal, BoxLayout::Middle, 0, 20));
+
+/* Add a slider and set defaults */
+Slider *slider = new Slider(panel);
+slider->setValue(0.5f);
+slider->setFixedWidth(80);
+
+/* Add a textbox and set defaults */
+TextBox *textBox = new TextBox(panel);
+textBox->setFixedSize(Vector2i(60, 25));
+textBox->setValue("50");
+textBox->setUnits("%");
+
+/* Propagate slider changes to the text box */
+slider->setCallback([textBox](float value) {
+    textBox->setValue(std::to_string((int) (value * 100)));
+});
+```
+
+The Python version of this same piece of code looks like this:
+```Python
+# Create an empty panel with a horizontal layout
+panel = Widget(window)
+panel.setLayout(BoxLayout(BoxLayout.Horizontal, BoxLayout.Middle, 0, 20))
+
+# Add a slider and set defaults
+slider = Slider(panel)
+slider.setValue(0.5f)
+slider.setFixedWidth(80)
+
+# Add a textbox and set defaults
+textBox = TextBox(panel)
+textBox.setFixedSize(Vector2i(60, 25))
+textBox.setValue("50")
+textBox.setUnits("%")
+
+# Propagate slider changes to the text box
+def cb(value):
+    textBox.setValue("%i" % int(value * 100))
+slider.setCallback(cb)
+```
+
+## "Simple mode"
+
+Christian Schüller contributed a convenience class that makes it possible to
+create AntTweakBar-style variable manipulators using just a few lines of code.
+For instance, the source code below was used to create the following example
+application.
+
+![Screenshot](https://github.com/wjakob/nanogui/raw/master/resources/screenshot2.png "Screenshot")
+
+
+```C++
+/// dvar, bar, strvar, etc. are double/bool/string/.. variables
+
+FormHelper *gui = new FormHelper(screen);
+ref<Window> window = gui->addWindow(Eigen::Vector2i(10, 10), "Form helper example");
+gui->addGroup("Basic types");
+gui->addVariable("bool", bvar);
+gui->addVariable("string", strvar);
+
+gui->addGroup("Validating fields");
+gui->addVariable("int", ivar);
+gui->addVariable("float", fvar);
+gui->addVariable("double", dvar);
+
+gui->addGroup("Complex types");
+gui->addVariable("Enumeration", enumval, enabled)
+   ->setItems({"Item 1", "Item 2", "Item 3"});
+gui->addVariable("Color", colval);
+
+gui->addGroup("Other widgets");
+gui->addButton("A button", [](){ std::cout << "Button pressed." << std::endl; });
+
+screen->setVisible(true);
+screen->performLayout();
+window->center();
+```
+
+## Compiling
+Clone the repository and all dependencies (with `git clone --recursive`),
+run CMake to generate Makefiles or CMake/Visual Studio project files, and
+the rest should just work automatically.
+
+On Debian/Ubuntu, make sure that you have installed the following packages
+```bash
+$ apt-get install cmake xorg-dev libglu1-mesa-dev
+```
+To also get the Python bindings, you'll need to run
+```bash
+$ apt-get install python-dev
+```

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+                  GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE

+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the

+
+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  Covered Software is provided under this License on an "as is"       *
+*  basis, without warranty of any kind, either expressed, implied, or  *
+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *
+*                                                                      *

+*  Under no circumstances and under no legal theory, whether tort      *
+*  (including negligence), contract, or otherwise, shall any           *
+*  Contributor, or anyone who distributes Covered Software as          *
+*  permitted above, be liable to You for any direct, indirect,         *
+*  special, incidental, or consequential damages of any character      *
+*  including, without limitation, damages for lost profits, loss of    *
+*  goodwill, work stoppage, computer failure or malfunction, or any    *
+*  and all other commercial damages or losses, even if such party      *

+*  jurisdictions do not allow the exclusion or limitation of           *
+*  incidental or consequential damages, so this exclusion and          *

+************************************************************************
+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a
+distinguishing version number.
+
+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+Licenses
+
+If You choose to distribute Source Code Form that is Incompatible With
+Secondary Licenses under the terms of this version of the License, the
+notice described in Exhibit B of this License must be attached.

+  *
+  * This module provides an interface to the Cholmod library which is part of the <a href="http://www.cise.ufl.edu/research/sparse/SuiteSparse/">suitesparse</a> package.
+  * It provides the two following main factorization classes:
+  * - class CholmodSupernodalLLT: a supernodal LLT Cholesky factorization.
+  * - class CholmodDecomposiiton: a general L(D)LT Cholesky factorization with automatic or explicit runtime selection of the underlying factorization method (supernodal or simplicial).
+  *
+  * For the sake of completeness, this module also propose the two following classes:
+  * - class CholmodSimplicialLLT
+  * - class CholmodSimplicialLDLT
+  * Note that these classes does not bring any particular advantage compared to the built-in
+  * SimplicialLLT and SimplicialLDLT factorization classes.
+  *
+  * \code
+  * #include <Eigen/CholmodSupport>
+  * \endcode
+  *
+  * In order to use this module, the cholmod headers must be accessible from the include paths, and your binary must be linked to the cholmod library and its dependencies.
+  * The dependencies depend on how cholmod has been compiled.
+  * For a cmake based project, you can use our FindCholmod.cmake module to help you in this task.
