[gtk+] Drop the shape window example in testgtk

[Matthias Clasen <matthiasc src gnome org>]

commit 535e604b91205fc7dc13b82727492ff182da0860

    Drop the shape window example in testgtk
    
    Not sure this can be rescued without root window coordinates.
    It is also somewhat inherently X11-specific.
