First off, let me say I've tried BOBs and disliked them immensely.

My question is:

  The only functions utilizing the blitter available in the graphics
library deal only with Blitter sources B and C, yet all of A, B, and
C are required for the cookie-cut method of pasting object blocks
with transparency.
  Is there any way of cookie-cutting AB+A'C FROM C... I hope I don't
have to learn assembly and obscure blitter queue stuff! 
  Yes I know Bobs were meant to do this, but for large shapes or large
numbers of shapes, Bobs are lousy.
