* src/hildon-pannable-area.c, (hildon_pannable_area_get_topmost): replaced gdk_window_get_children with gdk_window_peek_children, this way we do not have to free the list because it is not a copy.

(hildon_pannable_axis_scroll),
	(hildon_pannable_area_scroll),
	(hildon_pannable_area_timeout),
	(hildon_pannable_area_motion_notify_cb): Code refactoring, removed
	two parameters that were only used inside the
	hildon_pannable_area_scroll function.

	* examples/hildon-pannable-area-example.c,
	(get_sawtooth_label): Fixed small memory leak.
