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
