Fix:core: cancel drawing on resize request
This commit causes navit to cancel async drawing in case of resize
request. Drawing is started again after that. this should effectively
cause a redraw on subsequent calls to resize. Some graphics like qt5
call resize for both dimension changes if the wigdet get's resized.
