Very nice numbers. I'm especially excited about patches 1-6, which are
really just speeding up bitmap generation in general, pseudo-merges
aside. I think you could even have split those off into their own
series, and then built the final two as a separate topic, but I am happy
either way.
I looked through the patches and had nothing to complain about.
