Seemingly random colours were being painted as the background on the
terminal. This fixes MONO color blits.
Not really. For color blits it looks like we're doing the right thing here, at
least it works on VX800 as I'd expect it (when I change the bg_color to red I
get the characters with a red background, after applying your patch I get them
with a black background). To me it looks like we should set this register for
fillrect operations (as after your patch is applied I get a red backround for
the space where no characters are).
Thanks,
Florian Tobias Schandinat
