        * gdk/x11/gdkwindow-x11.c (gdk_window_reparent): Make
        this a total no-op when the new or old parent is
        destroyed. (#134230, patch from Soeren Sandmann)

        * gdk/gdkwindow.c (_gdk_window_destroy_hierarchy):
        For foreign windows in our heirarchy, call
        _gdk_windowing_window_destroy_foreign (window) and skip
        all the normal destruction logic.

        * gdk/x11/gdkwindow-x11.c gdk/win32/gdkwindow-win32.c:
        Move code to request destruction of a foreign window
        code into a separate _gdk_windowing_window_destroy_foreign().

        * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_finalize):
        Call GDK_WINDOW_DISPLAY() on the wrapper not on the
        impl. (Also from Soeren's patch)
