I don't mean to discourage you, but I this probably wouldn't be a very
good project.

The Glide API and 3dfx hardware is lacking in a number of areas,
particularly shaders.  Gallium was intended for newer hardware so it
wouldn't be a good fit for this older technology.

I'm sure there are other projects you could do related to
OpenGL/gallium if that's where your interest lies.  Other people on
this list might have some ideas.  I could probably come up with a few
otherwise.  What do you think?
