> Source/WebCore/ChangeLog:8
> +	   Mark layers as opaque in a very simple case - any child renderer has
an opaque background and covers the entire composited bounds.
RenderLayer::contentsOpaqueInRect has been implemented conservatively, i.e. it
errs towards returning false negative.

It's not "any child renderer" currently; it's just the layer's main renderer.
