Thanks! I don't know if it was the "bug fix or two" or the
fill-rectangle optimization that did it, but now I don't any longer
notice any update glitches in HEAD gtk-demo. (Previously, in
cairo-using GTK+ HEAD on Win32, I used to get black areas here and
there all over the place.) Even GIMP mostly works with HEAD GTK+ on
Win32 now. (The stuff that doesn't work is because of some hacks not
related to cairo that I'm testing.)
