Works with stock 3.7 and 3.8 image.
I have tested this (worried because its my first upload!).

As in the SqueakMap description, this is a first attempt,
it works with simple svgs, and more complex ones (maybe with artifacts).
It is far from complete (no text support for starters, and enders,
probably!).

Additonally, Arcs are approximated with Bezier curves and some of the other
SVG privitives are
not yet directly supported.

If you wish to test then some of the samples provided with
Inkscape (http://www.inkscape.org/) work ok (especially tux.svg!).

Hope this helps.
