This works great! This is very close to the effect I was trying to
achieve, and almost completely elminates the jarring "popping" effect.
Interestingly, it seems to look best on Firefox, as Chromium and Opera
seem to render the innermost stop as a small hard-edged circle,
whereas in Firefox, it actually starts out as invisible. But I think
it's certainly better than it was before.

I actually had trouble understanding how the algorithm worked on first
read-through. The liveliness of the NodeSet is important. But I like
the technique of making two innermost stops with offset 0, so that the
first offset starts out invisible, and then adjusting the offset of
the second stop so that the innermost gradually becomes visible. Very
nice.

Thanks for your help!
