Ah, yes.  Padding too.   You could instead ask for the computed style 
width, but I'm not sure whether that does what it does in Gecko (return 
the actual used width) in all browsers.

It might be good to create some APIs to query these sorts of box 
properties.  Anne, are you on this list, by chance?  ;)
