borders and padding

Anybody got thoughts on how to handle borders and padding now that
they're out of the core?

I wanted to just trap fill for borders but now I'm unsure whether that's
wise given that I've no idea how we determine whether a value put to
fill is a colour or an image resource.

Also, should padding be part of border?  (An invisible border?)  Or
would it be better handled using a transformation rather than extra
boxes.  We can either wrap the <content/> in a 3x3 grid of boxes (with
colspan set of course) or we can somehow shift the <content/> to the
desired x,y and make sure it's never larger than [width-2x] and [width -
2y].
