Bug 640195 in GDK exposed by gnomine; fix included

[rufus hamade <rufus myfanwy org uk>]

Hi all, 

Gnomine currently suffers from a rendering issue caused by a bug in GDK.  Details:
https://bugzilla.gnome.org/show_bug.cgi?id=640195

I think I've tracked down the issue and prepared a fix, which I've attached to the bug and attached here.  Basically, gdkwindow-x11 was not using the impl window when deciding how big to make the cairo surface for a widget.
If you think this patch is the correct one, I'll check to see if the same fix needs to be made anywhere else.

HTH.

Subject: [PATCH] Fix gdk_x11_ref_cairo_surface so it uses the impl_window's dimensions when creating a cairo surface.
