Why whould it "stop working well" with monochrome just because we use a 
different internal depth? And as I said, both QuickTime (raw and RLE) 
and BMP use pal8 exclusively for 1 bpp files. If you're willing to 
change the logic for these other formats as well, please go ahead. I 
won't do it.

Why shouldn't we be consequent and do the same thing as for other file 
formats and other depths? It's over my head.
