Spec text is now:
A non-zero blur distance indicates that the resulting shadow should be blurred, such as by a Gaussian filter. The exact algorithm is not defined; however the resulting shadow must approximate (with each pixel being within 5% of its expected value) the image that would be generated by applying to the shadow a Gaussian blur with a standard deviation equal to the half the blur radius
