Huge dumb drop. State:

Huge dumb drop. State:
- Color buffer clear is accelerated, but flickers (possibly caused by a
  recent DDX or Mesa change or bad merge)
- Everything else uses software fallback rendering
- There should be no clipping-related artifacts with the
  sw-clipspan-fixes.patch against Mesa (posted on dri-devel)
- Multiple clients should be rock solid with a DDX patch that is soon to
  come (soon = within the next hour or so)
