In the spec, `fill` and `stroke` are supposed to be a shorthands for various properties. But since the spec is still a working draft, and neither Firefox or Chrome support the `fill-color` or `stroke-color` properties, we'll stick with `fill` and `stroke` as simple colors for now. Also, note that SVG expects things in "user units", and we are assuming that 1px = 1 user unit for now.
