Re: [css3-background] does border-radius round the border-image ?

I think border-radius should clip the border-image, just as it clips  
the background.  In many cases I believe the border-radius should clip  
the foreground too.  Border-image alone is not able to dictate this  
clipping behavior, so a designer *is* going to need to set both in  
order to clip the background and foreground content, regardless of  
fallback intentions.

I think it's inconsistent that this clip effect, which we'd like to  
apply to the whole box in the case of content like images, would "turn  
off" just for a single piece of the box (a specified border image).  I  
don't think the fallback use case is particularly interesting or  
relevant here.
