Thanks, David.

I think you're right that we'll want that.

I had imagined a distinct matrix type for doing projective
transformations of surfaces. Maybe that would be too messy though.

Absolutely. Hopefully, this falls into the category of API additions, so
it should be easy to do between "API Shakeup" and "1.0 release".

Should also just be an API addition, so simple enough to do.

I've been going through, reviewing, and writing ChangeLogs
myself. Besides the little pieces I didn't commit, I'm now up to the
pattern type changes, and I think we're blocking on a resolution of
that debate.

Owen has agreed to fix up the win32 backend as needed after your
patches land.

The quartz backend has apparently been broken ever since Owen's big
font changes just after 0.3.0. So, we'll need someone to give it some
attention, or it will just be disabled in this snapshot.
