This patch was applied before but reverted because it caused
	problems, we have changed the main condition and tested the
	regressions we detected before and they work ok. We have done a
	complete review of the topmost algorithm in order to get a more
	general solution.

        * src/hildon-pannable-area.c,
        (hildon_pannable_area_get_topmost): Added a new parameter to
        filter the the windows that do not include those events.
        (hildon_pannable_area_button_press_cb),
        (hildon_pannable_area_button_release_cb),
        (hildon_pannable_get_child_widget_at): Reviewed the call the the
        topmost function, we have added the new parameter.

        Fixes: NB#97458 (Pannable area prevents propagation of button
        press events)
