Ah, that is actually a good point. I didn't quite understand the  
syntax, but the need is real. I've had cases where the background PNG  
loads a little too late after the element is displayed, or has a  
problem loading at all, or where Webkit decides not to show it at all  
because a form has begun to be submitted. It would be nice in such  
cases to have a solid fallback color that is NOT used when the PNG  
(with variable translucency) is present.
