The reason I left the 'pixman' structure intact was to make it a bit
easier to split pixman back out when it's ready to stand on its own. I
don't think it will be that long, and I wanted to preserve its separate
ChangeLog and make the different license very clear to developers.
I agree it's a bit confusing to have multiple src/ directories; I'd like
to preserve the cairo/src directory as that makes it possible to extract
old versions of cairo correctly. That leaves us with changing the
pixman/src directory name, which seems fine to me. I'd like something
other than 'pixman' though

As long as the files get rebuilt with the new pixman.h, it should 'just
work'. Do you have the Makefile.am patch that includes pixman in the

I'm not sure the extra noise would really help all that much.
