You're welcome.

It sure looks a lot nicer now (though I hardly ever work in 8bpp ;)

Yeah - the problem is that there is only so much you can do with a balanced
2x2 stipple pattern. It might be worth checking if a better effect can be
achieved using different patterns - note that for 8bpp you could actually
get 4x4 pattern (since the pattern fills one word you can pack 4 different
pixel values in one word) but it's also limited in the number of colors that
can actually be represented. If you find a better method of generating the
dither patterns let us know!

Good point. Thanks for mentioning it!
