Re: [css3-background] Where we are with Blur value discussion

Ins't conformance is that, where the shadow is measurable, it measures correctly as being equal to the result of a gaussian blur of the given radius, to the accuracy of expression of the implementation (e.g. 8-bit pixels).

This completely avoids the question of an edge, which doesn't exist in a gaussian anyway.
