Well, I'm curious about the coalesced update thing. The only ref I

doesn't find any APIs with "coalesce" in their name that are drawing-
related. Can you give me a pointer?
Odd, I got these as the first hits for "coalesced updates":
<http://developer.apple.com/mac/library/technotes/tn2005/tn2133.html>

I'd try to elaborate, but I'd probably embarrass myself because I
haven't actually looked closely at this. I just remembered someone
mentioning it once or twice upon a time.
