Are you saying that there isn't support for dithering from 24 bit
when uploading pixmaps? (Even Windoze does that... Don't know enough
about X, GDK and GTK+ to tell exactly where it would be done here.)
Anyway, I have some dithering code lying around, but it's meant for
games rendering directly to the VRAM, and deals with packed pixel
formats such as 5:5:5, 5:6:5 and all that hardware specific crap. (No
standard.) Not very useful in this case, I'd guess...?
