Code review comment for lp:~compiz-team/compiz/compiz.fix_1024304

I have used the ppa containing these changes since the beginning and could confirm the performance improvements using Phoronix Test Suite (and of course my subjective feeling). Comparing benchmarks of compiz 0.9.9.0 and the branch containing the improvements (both disabled "unredirect fullscreen windows") clearly shows that there is an substantial performance improvement.
Part of my benchmark results can be downloaded here:
