Alan Ruttenberg wrote some code that uses GWorlds to do off-screen
bitmaps. It will take a little work to make it fully general, and it
won't work on machines without 32 bit quickdraw, but it will probably
be useful to many people. He wrote the code as a contractor for Apple
so it should be ours to distribute. Alan, please tell us more.
