Connect the "destroy" signal so that the 'window' pointer is set back to

2007-06-29  Ryan Lortie  <desrt@desrt.ca>

        * tests/testgtk.c (create_composited_window): Connect the "destroy"
        signal so that the 'window' pointer is set back to NULL (like for the
        other examples).

        * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_finalize): Don't
        destroy the Damage here.  By finalize() XDestroyWindow has already
        been called (and took the Damage with it).

        Bug #452046.
