- 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.
- Add libdrm and libdri. Portions of the DRI extension are stubbed out.
- Use the DRM in the ATI driver when available. This provides a minor
performance improvement in x11perf, and opens the possibility of using
the 3d hardware for acceleration in the future.
- Implement solid fill acceleration for Composite in KAA.
- Implement Blend hook for Composite and use it on r128.
- Fix a bug of mine that resulted in overuse of offscreen memory.
- Fix many miscellaneous bugs in ATI driver and add PCI IDs.
