/**
** Supermodel
** A Sega Model 3 Arcade Emulator.
- Finished cleaning up and optimizing the 2D renderer. - Fixed up color offset register support for new 2D rendering system. Now maintains 2 computed palettes for layers A/A' and B/B'. - Fixed a minor bug in InitPalette(); VRAM was not being typecast properly. - Fixed specular lighting bug that occurred on some OpenGL drivers because integers were not being interpreted as floats in the vertex shader. - Began to update copyright date in some files. - Graphics modules now use the C++-style names for C standard library headers (e.g., stdio.h -> cstdio) consistent with the rest of Supermodel.

// Vertex shader
Rewrote 2D renderer and fixed 2D layer priorities, stencil mask clipping (Scud Race 'ROLLING START'), and cleaned up code. Unfortunately, the new code is about 50% slower, mostly due to the need to perform stencil clipping after scrolling.
