565. what it does is it's a half-way house between no dither and "small
dither mask". what is does is change the "rounding" between odd and even
lines. the resolt is not as nice as small (or large) dither mask - but its
almost "good". it gives a horizontal-blinds like look to dithering. it's
almost as fast as no-dither in my tests on a core2 (of course making lots of
use of branch prediction or conditional instructins - whihc arm nd x86 have).
