Might not be necessary: http://git.gnome.org/browse/gtk+/commit/gdk/win32/gdkpixmap-win32.c?h=gtk-2-24&id=ba8c4bb049b36b3707c2c8f22c5c66b497e2d2cf
Gtk_-2.24.9 just got released last week. I'll blind-change defaults.sh to use it in a few minutes and we can cross our fingers. If the nightly builds, Geert can try it tomorrow and barring any issues it can go in the release on Monday.
