    gesture: Fix gtk_gesture_get_bounding_box
    
    When we stopped translating event coordinates in-place,
    this function inadvertently started returning surface-relative
    bounding boxes instead of widget-relative ones, as expected.
    
    Fix this by using the widget-relative coordinates that we
    already store.
