  Overflow does affect layout, doesn't it? If my image bordered  
element is inside another element that is floated, then the width of  
the floated element changes based on whether or not the overflow from  
the border-image is widening it or not. That then affects what other  
elements can sidle up alongside it.

Also, suppose my BODY element has 16px of padding and no margin or  
border. Now I put a 32px wide border-image around it with a 32px  
offset. In that case, I would expect the border-image to be clipped on  
all four sides (or at least three). If it was clipped on the left and  
top but scrollable to the right and bottom, that would just be weird.
