It really seems like it should be a reference as the pointer can't be NULL. To
avoid hidden copy, we should make OutlineRectInfo NonCopyable.

Changed the return to be a reference. I didn't change OutlineRectInfo to be
non-copyable as that's how I'm currently setting the OutlineRectInfo into the
map. Is that wrong?
