Huh? I don't see how that solves the problem.

I'm talking about .svg art blending with the existing system scheme. 
Think about a Qt style, for drawing a frame you usually take various 
shades of the base color. Now imagine I am doing that in .svg, I know I 
want frame element X to have the color 'shadow shade of window normal 
background'. How do I express that?

That was what Parker mentioned originally. The problem is supporting 
that in the editor without resorting to using a text editor on the .svg. 
I don't believe Inkscape supports (*easily*!) giving objects arbitrary 
color names, does it?

So... the gradient control points are a function of the element's 
bounding box? Or what? It's a neat idea, but I'm not sure how practical 
it would be. (And anyway, I think that is an orthogonal problem.)
