[svgwg] Interpretation of how to handle surfaceScale in feDiffuseLighting when rendering to different sizes (#873)

Omnikron13 has just created a new issue for https://github.com/w3c/svgwg:

== Interpretation of how to handle surfaceScale in feDiffuseLighting when rendering to different sizes ==
https://www.w3.org/TR/SVG11/filters.html#feDiffuseLightingSurfaceScaleAttribute

There seems to be inconsistent ways that renderers are handling this. Even with `kernelUnitLength` set I'm seeing visually different results when rendering to different resolutions in e.g. Chrome vs. Firefox and Inkscape vs. resvg.

When raising the fact that I would expect visually similar output without having to manually modify the value of `surfaceScale` for different resolutions with the authors of resvg they noted that the spec is not explicit about how to handle this and suggested I raise the issue of clarity in the spec here if we want consistent output across different renderers implementing the spec.
