I don't think the units need clarification, really -- I think all the
width/height things when talking about faces would naturally be assumed
to be pixels.

But I have no idea what a negative `line-width' would mean, and that
needs documentation.  I've skimmed the C code that deals with
`line-width', but it's still rather obscure to me.

Could someone who knows what a negative `line-width' in :box means
document this in the manual?
