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

That hint helped.

I have now added (not comitted yet) a html-property render-pict-as
which has the
values 'png-images and 'svg-images.

The following example, where I set the style for the title works, in
the sense that svgs are
being generated.

#lang scribble/base
@(require scribble/core scribble/html-properties)
@(define svg-style (make-style "svg" (list (render-pict-as 'svg-images))))
@(require (only-in pict standard-fish))
@title[#:style svg-style]{@(standard-fish 100 100)}

However I can't figure out how to set a style for the part that represents
the whole Scribble document.
