Gerd Hoffmann a89fe6c329 vga: catch depth 0 
depth == 0 is used to indicate 256 color modes.  Our region calculation
goes wrong in that case.  So detect that and just take the safe code
path we already have for the wraparound case.

While being at it also catch depth == 15 (where our region size
calculation goes wrong too).  And make the comment more verbose,
explaining what is going on here.

Without this windows guest install might trigger an assert due to trying
to check dirty bitmap outside the snapshot region.
