    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.
