More Win32 redrawing problems

[John Lindgren <john lindgren aol com>]

Hi,

I have another problem with GTK+ widgets not redrawing properly on
Windows.  It seems that inactive windows are trying to save CPU time by
not drawing on obscured regions, but somehow they get it backwards --
the region they don't draw is the mirror image (horizontally) of the
region that is actually obscured.  This video illustrates the problem:

Martin was helpful in pointing me to a Cairo patch for the last
redrawing issue I ran into [1].  It would be awesome if someone knows of
a patch for this one also.
