ba10615722 Allow compiling containers on Xbox 
Obviously GLdc doesn't work on XBox but the containers are fairly generic and are (ab)used
in the Simulant engine which does compile there.

0cd447dbcf don't waste a full byte on mirror/flip setting 
moved MIRROR bits into bits 2 and 3 of what used to be `uv_clamp` member of TextureObject
renamed `uv_clamp` member to `uv_wrap`
updated and commented code accessing `uv_wrap` for both clamp and mirror settings

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
