    a view for input only - forwarding all events to another object.
    This kind of view can be used to be laid ontop of another view to catch all
    input. (Interface builder)
    NOTICE: the event forwarding is a leftover from times when not delegation mechanism
            existed - it will vanish - use delegates for new code.
