I don't know what the mac does to download it's patterns, but one of
us has written a PostScript driver that creates its own pattern fills.
One has to figure out the bit map for the pattern and send it to PostScript
in hex. To get a fine-scale pattern you need a lot of bits, coarser
patterns (fewer bits) can be enlarged but look cruder.
