    gtkgesture: Do not ignore events from other GdkWindows than the widget's
    
    There's GDK grab situations (eg. pointer motion outside the grab window
    in combination with a GTK+ grab) where a gesture may receive events from
    windows that are not the widget's.
    
    The _update_widget_coordinates() still does work for those situations, so
    just let these events go through instead of ignoring them.
