[racket] Generating svg-images rather than png-images from Scribble

The relevant method is `render-part`. The `d` argument to the method is
a part.

In the same way that `current-version` is parameterized by extracting a
version from the style properties of `d` (see the inherited
implementation of `extract-version` from "base-render.rkt"), you could
set the parameter that controls image rendering by looking for
'png-images or 'svg-images in the style properties of `d`.
