I tried just fixing absoluteClippedOverflowRect() on RenderSVGRoot, but that's
insufficient.  We have to fix it all the way up the chain.  What is dirtying
way too much is not the root, but rather the children.  We need a way to access
your parents clip rect as a child.  Possibly a clipRect() function or an
applyClipToRect(rect) function which can walk up the parent chain.  We could
also use/abuse the LayoutState optimization if we were careful.
