Re: [svgwg] Radial gradients: "fully overlapping" vs "focal point on the edge" - which takes precedence? (#648)

`fr` was new in SVG 2, and designed to match with canvas.  But it's possible that the default state (`fr="0"`) does not match against what SVG 1.1 does.

I suspect that some or all of the browsers haven't changed their implementations to support `fr` at all.

Which would mean that the result is more about what to do when the gradient vector has length zero and/or when multiple stops compute to the same final position on the gradient vector. I do recall in testing that there was cross-browser incompatibilities for linear gradients in this case, and we made a point of specifying behavior in SVG 2, but I don't know whether bugs were filed on the non-conforming browsers.
