Sweet!

I'm sad that I still don't have time to look this over right now, but I
really hope others will grab it and try it out.

I don't remember if I said this already: I asked Keith Packard about
image formats and he said that they're well documented in the early
sections of the protocol specification. I think he said that stuff is
right after the screen information. Well, I looked through my old 1988
edition of the "X Window System" book, and don't see anything useful. I
haven't had time to look in some more modern X protocol reference, so
maybe you'd like to try that.

Thanks much for posting it so everyone has an opportunity to help.
