I did some testing of these with compiz and they don't actually fix the
problems with unredirecting fullscreen windows on my r300.
Some further thought about the issue leads me to the conclusion that the
only thing these patches really fix, is getting a more fresh snapshot of
the front buffer into the fake front buffer for those drawables that
didn't initiate the swap.
The real problem is that the front buffer pixmap and name might have
changed between GetBuffers and SwapBuffers. I cooked up a couple of
quick and dirty patches for radeon to fix the problem for me. I'll see
about cleaning them up later, but here they are just for reference.
