GLdc: an OpenGL implementation for the SEGA Dreamcast

This should be much faster as matrix loading is now minimized. Also splits transform from perspective divisionn to lay the groundwork for near-z clipping. This also fixes GL_POLYGON submission. Lighting can be made faster, this doesn't change the lighting algorithm, but the matrix changes should speed things up. |

GLdc
This is a partial implementation of OpenGL 1.2 for the SEGA Dreamcast for use with the KallistiOS SDK.
It began as a fork of libGL by Josh Pearson but has undergone a large refactor which is essentially a rewrite.
The aim is to implement as much of OpenGL 1.2 as possible, and to add additional features via extensions.
Things left to (re)implement:
- Near-Z clipping (Tricky)
- Spotlights (Trivial)
- Framebuffer extension (Trivial)
- Multitexturing (Trivial)
- Texture Matrix (Trivial)
- Mipmapping (Trivial)
Things I'd like to do:
- Use a clean "gl.h"
- Define an extension for modifier volumes
- Support
GL_ALPHA_TESTusing punch-thru polys - Add support for point sprites
- Optimise, add unit tests for correctness
