    clutter: Shuffle handling of IM reset on button presses
    
    Unfortunately we cannot do this generically since the target of the
    button/touch press does matter, e.g. tapping on the OSK, or clicking
    the IBus candidates window. These situations should not trigger a
    reset.
    
    So be more selective about the situations where button/touch presses
    trigger an IM reset, in the case of ClutterText these are still clicks
    inside the actor, for Wayland's text-input it is when clicking the
    surface that has text_input focus.
    
    For all other situations where clicking anywhere else might make
    sense to trigger an IM reset are covered by the focus changing paths,
    that also ensure a reset before changing focus between surfaces/actors.
