Does anybody have any idea how QuickDraw's regions are implemented internally?
Run length encoded bitmaps? Lists of q.d. primitives? Enclosing boundry
chains? They're such a nice idea that I want to incorporate them into
my own non-68000 gaphics routines. (The Apple QuickDraw documentation is
excellent, but it does not document the internal representation of either
regions or pictures. I suppose this is on purpose, since these structures
took a long time to invent. . . .)

I'm going try to determin how regions work by experimentation, next time I
have a couple of days free, but I was wondering if anybody else has looked
into this....
