    StImText: remove two references to old clutter bugs
    
    Remove a workaround for clutter_actor_get_transformed_position() not
    working inside paint(), and remove a comment about
    ClutterText::position not being properly notified, since it is now.
    (However, it doesn't seem worth it to rewrite the code to use
    notification, since that would actually end up being more complicated
    than the current solution.)
