[css3-background] Color of ridge/groove/inset/outset border styles

Hi,

A very low-priority, but annoying detail:

The ridge, groove, inset and outset border styles are defined with 
"Looks as if …" and leaves not hint as to how to do that. The rendering 
in different implementations varies a bit but that’s fine, the normative 
definition doesn’t need to be more precise.

Still, I’d like the spec to have a note that gives an algorithm 
describing how to generate two colors (one dark and one light) from a 
single specified border-*-color in order to get the example rendering in 
Figure 5. I came up with *something* for WeasyPrint, but it just looks bad.
