    stage: Process state update event immediately
    
    The _clutter_stage_update_state() function is currently putting events
    into the Clutter event queue. This leads to problems in the gdk
    backend because there are assumptions upon the numbers of queued
    events, and how many of them should be moved from the main event queue
    to the ClutterStages' event queues.
    
    This change triggers the processing of the state update events on the
    stage directly, so the main event queue retains the expected number of
    events.
