The CR says that *backgrounds* determine the appropriate curve to
clip to via 'background-clip'. It does not say which curve other
clip effects use: that is determined by the property doing the
clipping. In the case of 'overflow', the definition of 'overflow'
says which edge to clip to. The 'border-radius' property just
alters the shape of that edge, it does not change which edge.
