Move the transform and lighting code to two new directories
math: Provides basic matrix and vector functionality that might be useful to multiple software t&l implementations, and is used by core mesa to manage the Model, Project, etc matrices. tnl: The real transform & lighting code from core mesa, including everything from glVertex3f through vertex buffer handling, transformation, clipping, lighting and handoff to a driver for rasterization. The interfaces of these can be further tightened up, but the basic splitting up of state and code move is done.
