The problem is that the line thickness doesn't *scale*.  You want a shape
where the middle ring is as thick as the distance between the other two.
Shapes don't do that kind of constraints.

I know not how to make a real donut shape without programming it.  I doubt
that SVG will let you make polygons with holes.

There are several good suggestions on the recent parts of the mailing list.
