    GdkWindowX11: the root window is not a toplevel
    
    The macros we had for checking for toplevel windows were passing
    through the root window, which was not intentional and meant that
    for the root window WINDOW_IS_TOPLEVEL() returned TRUE but
    window->impl->toplevel was NULL, causing gdk_window_create_cairo_surface()
    to crash.
