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.
