  Unfortunately they sometimes leave it shut off, meaning that other
applications seem to have to check whether it's true.   At least, I'm
now getting bug reports about my app losing video in obscured portions
since we only paint the colour key on map. . .

  Anyway, point being that tvtime will in the next version always paint
the colour key to avoid this problem. :)
