Set the colormap on the offscreen pixmap
Set the colormap on the offscreen pixmap

Clutter started asking for an ARGB visual on master since 1.1.5, so we
need to explicitly set the colormap on the pixmap returned by the
offscreen machinery in GTK+. GTK+ should do this internal, and it has
been fixed, but there hasn't been a release with the fix yet.
