	I need source code (or at least an algorithm) to 
flip a dpaint brush horizontally.  Flipping a brush vertically
is easy, but to flip it horz. requires bit manipulations (I think)

	Is the best way to do it : go across each row of image backwards from
right to left -- pushing each bit on a stack and then popping it off into
the new (reversed) image?

Detailed descriptions or source code welcomed.
Specifically, I want to reverse a brush in 320 X 200 EHB (6 bit plane) mode
(I know that any paint program does this, but I want to be able to do it inside
of a program)

Thanks
