This is breaking a little backwards compatibility but on something we're surely not using anywhere else anyway - if a scene object has already been laid out, don't do it repeatedly, which was then causing extra dirty rectangles, especially when we scrolled. The actual breakage of compatibility comes that I took out the otherIndicators argument on SceneObjectIndicator.layout, which we weren't using anyway.
