Re: [fxtf-drafts] [filter-effects] Clarify "smoothing technique" for feSpotLight's limitingConeAngle

Not sure what you mean by "adapted" here. What the Gecko code referenced above does is the minimum to get a cone-limited spotlight, so all implementations that support `limitingConeAngle` ought to do that. (It's in the spec already.)
As mentioned in my [earlier comment](, Skia also implements a "falloff", which is essentially another cone, and the light cast in between these two cones are scaled (attenuated) by a factor (derived from `-L.S` and the two cone angles.) That's the only adaption going on (in both the SW and HW implementations.)
