Issue 3293: Add point-and-click to SVG output

Seems to work here, but the link coloring is distracting.

Don't change point-and-click elements' color

Cool, that looks much better than my previous patch.  Thanks!

Unfortunately, although firefox and inkscape handle the resulting svg file quite
well, it isn't a valid file.  According to the w3c validator
  http://validator.w3.org/check
svg 1.1 cannot contain a <a> without an xlink attribute.  Now, we use 1.2
(presumably svg 1.2 tiny?), but so far I've been unable to determine if xlink is
optional or not in 1.2.  Casual browsing of programming forums suggests that we
should target 1.1 anyway, since that's what has the most support.

Pfffffft.  Well, so much for the easy way out.  At least I am getting closer to
finding my way around stencil interpretation.  With a bit more investment of
time, I should be able to just change the stencil callbacks to something saner. 
But it'll likely take at least one or two weeks before I can really invest more
time here.

Make call of no-origin conditional
