    clutter/main: Change picked actor before emitting crossing events
    
    Updating the state before emitting the CLUTTER_LEAVE event allows its
    handlers to query the pointer actor, and avoid getting the same actor
    again. Conceptually, this makes picking more "atomic", and the events a
    notification of the change.
