It does as it's based on the same acceleration paths from Xgl so it's
reduced the effort to get a GL acceleration path up and running.

Optimisation is always the fun stuff in GL, so we could remove or
optimise glitz, but the code works as it stands and optimisation is
always a never-ending game.

Both myself and Jose have tested successfully on 945G hardware, and it
works really well with current Mesa/DRM head & xserver glucose-2 code.

The wiki page shows it's current status and there's a couple of issues
to get resolved, before I want to bring to master.
