* clutter_x11_handle_event:

* into external X11 event processing (for example, a GDK filter
* function).
*
* If clutter_x11_disable_event_retrieval() has been called, you must
* let this function process events to update Clutter's internal state.
*
* Return value: #ClutterX11FilterReturn. %CLUTTER_X11_FILTER_REMOVE
* indicates that Clutter has internally handled the event and the
* caller should do no further processing. %CLUTTER_X11_FILTER_CONTINUE
* indicates that Clutter is either not interested in the event,
* or has used the event to update internal state without taking
* any exclusive action. %CLUTTER_X11_FILTER_TRANSLATE will not
* occur.
*
* Since: 0.8
