Eric Anholt 01e9cc858a - Add glx visuals code based on XFree86's Radeon driver. 
- Reserve areas for back/depth/span when USING_DRI && GLXEXT. This would be
    better in a TransitionTo3d, but we'd need to work with the offscreen
    memory manager for that.
- Misc. fixes to ati_dri.c for DRI+GLX. Needs more work still.
