+ * tests/icles/stress-xoverlay.c: (toggle_events), (create_window):
+ Add a method to the XOverlay interface to allow disabling of
+ event handling in x[v]imagesink elements. This will let X events
+ propagate to parent windows which can be usefull in some cases.
+ Be carefull that the application is then responsible of pushing
+ navigation events and expose events to the video sink.
+ Fixes: #387138.
