Detailed Description

Device driver function table. Core Mesa uses these function pointers to call into device drivers. Most of these functions directly correspond to OpenGL state commands. Core Mesa will call these functions after error checking has been done so that the drivers don't have to worry about error testing.

Vertex transformation/clipping/lighting is patched into the T&L module. Rasterization functions are patched into the swrast module.

Note: when new functions are added here, the drivers/common/driverfuncs.c file should be updated too!!!
