Good point. So then how do you determine the "appropriate" curve for  
border-radius overflow clipping? The CR says it is based on  
'background-clip', but you are saying that should not affect overflow.

However 'border-radius' determines its clipping shape, it should work  
the sane if you have 'border-radius:0' (the initial value). Am I  
missing something here?
