If you are getting moire patterns, then the halftone algorithm is not very
good.  As I said, ordered dither doesn't have to give moire, and there are
different methods to do ordered dither too...

I did this work some 10 years ago, I would have thought it would be old hat
by now!  I may even still have the microcode from back then...but it would
take some digging.
