    StContainer: simplify focus navigation
    
    When navigating from a non-immediate descendant of a container, we
    were attempting to use clutter_actor_get_transformed_position() to get
    the exact position of that actor relative to the container, but this
    did not really make sense, since we would be using the position of
    the intermediate container when navigating back.
