Subject: [PATCH] Track bounds changes for our underlying sprite in such a way
 that we dirty things properly if they do. Simply stealing our target sprite's
 _bounds will not result in the necessary calls to addDirtyRegion() if they
 change due to calls to setLocation() on our (now unmanaged) target sprite.
