70e0d503a9 Fixed incorrect alpha vertex color value. 
- _readColorXXXARGB() macros were being passed the incorrect input index
  for the alpha channel from the outer macros, fixed.
- Thanks for finding it, UnknownShadow200!

b09e630304 Implemented support for all vertex attribute fmts. 
1) GLdouble was incorrectly being treated as GLfloat which is now broken
   with -m4-single as default. Fixed.
2) Implemented all missing double-precision vertex attribute reader
   functions.
3) Implemented all missing vertex reader/extracter functions for
   unsigned/signed ints and unsigned/signed shorts.
4) Added (void) argument lists to every function missing them.
    - Not the same as accepting no arguments in C, as with C++.
5) Added KOS's __restrict to software.h so it can be used in common code.

56f5b24d85 Fixed OpenGL Fog implementation + Added New Sample 
- Redid fog.c OpenGL fog back-end implementation
    * only reconfigure fog values when changed
    * properly clamp between 0.0f and 1.0f colors
    * error out on negative densities
    * separate fog statics became single struct
- Added Nehe16 example (adapted from KGL)
    * Made spinning much faster (so you can see it better)
    * fixed a few issues with KGL code (invalid GL enums, lol)
    * swapped to new controller API
    * added #ifdef for non-DC file paths

49f2f0917b Nehe20 Build Fix + Warnings cleanup for GCC14.1.0. 
Newest toolchain is bitchier, so I wanted to go ahead and clear up all
of the warnings from building GLdc and the various examples...

1) Set CMake CXX standard to 14 instead of 11, since CXXFLAGS were
  enforcing that language standard anyway.
2) Fixed a bunch of strict aliasing violations in immediate.c: glVertex3f.
3) Removed or commented out lots of unused variables.
4) Fixed some "suggested inner braces on initializer" crap.
5) Fixed a bunch of signed vs unsigned pointer assignments.
6) Fixed several printf() warnings from using %d with int32_t (needs to
   be %ld for long int).
7) Fixed build issue with Nehe20 from not including kos.h for the
   KOS_ROMDISK macro.
8) Fixed some signed vs unsigned comparison mismatches in C++ template
   instantiations within clipping tests.
9)
