The SVG spec includes support for starting an animation based on hyperlinking. See:

http://www.w3.org/TR/SVG11/animate.html#IndefiniteValue
http://www.w3.org/TR/smil-animation/#HyperlinkSemantics

Also at least one of the W3C SVG 1.1 Full testsuite tests requires this:

This bug depends on being able to seek to an earlier point in the timeline: bug 492458.

We basically need to do two things:

 * When we start the timeline after the document is loaded, we need to
   check for a hash and trigger any animation as applicable (be careful
   of pauseAnimations being called before load, that on unpauseAnimations
   things work correctly).

 * We need to have the document listen for 'hashchange' events and trigger
   animations as appropriate. Something like:

  nsCOMPtr<nsIDOMEventTarget> evtTarget = do_QueryInterface(doc);
  evtTarget->AddEventListener(NS_LITERAL_STRING("hashchange"),
                              mEventListener, PR_FALSE);
