[clutter/clutter-1.18] gesture-action: Ignore any other event than press/update/release ones

    gesture-action: Ignore any other event than press/update/release ones
    
    CLUTTER_ENTER/LEAVE might be processed too, leading to accounting of the
    NULL sequence (ie. pointer) in the gesture, and fooling the gesture with
    a static extra point that wouldn't go away.
