I think BORDERLESS is still incompatible with SUPER_BITMAP since it is
documented that SUPER_BITMAP must be GIMME_ZERO_ZERO.

But as I proved to somebody else today, there is almost no overhead
for adding a normal BACKDROP|BORDERLESS window to a CUSTOM screen.
It does not require separate bitplanes.
