	This is another plea for help. 

	I need to be able to blit a piece of one picture onto another piece
of a a picture. Here the catch. I want to be able to see through the parts of
the picture that were black on the source of blit.
	In other words. If the source part of the blit was a ring with an open
center of the background color, palette 0, when it was blitted to the
destination only the NON-ZERO parts were copied. The result would be a ring
overlayed on the original destination picture. 

	Any help at all would be greatly appriciated. Also I can handle lots of
mail so please anyone with any ideas or help please let me know.

	Thanks in advance,
	Joshua

P.s.  Anu source in C or in ASM would be greatly appriciated. Thanks again.
