I've attached a patch against the current SVN version of renderSVG.py
to support making links on closed SVG paths.  Without this only the
simplest of vector shapes had working links (rectangles, polygons,
circles, etc), but by supporting closed paths this lets the user
create any complicated shape - and have it linkable :)

At the end of the email is an example of how this might get used.
