    clutter: Make crossing events unstoppable
    
    These events are not meant to be ever silenced away, every actor
    that is meant to receive one should do so. Make it sure that those
    events cannot be stopped, despite the event signal handlers return
    values.
    
    This opens the debate about whether crossing events should be
    ClutterEvents, since they are more and more uncommon at being one,
    maybe this notification mechanism should be taken away from the
    event machinery, but that's something for future refactors.
