Well, so layout is required before painting or before grabbing rects from the rendering tree.  Because layout is how the RenderObjects figure out where they are.  So it makes sense that you'd need to call updateLayoutIfNeeded (I think that's the name?) or updateLayout right before grabbing a rect off the rendering tree (or you might ASSERT), and certainly before painting.  But you wouldn't after you're done since nothing you're doing in this patch should invalidate layout as far as I can tell?
