  1. ISSUE-131: Fix definition of blur radius for box-shadow [CSS3 Backgrounds and Borders] (from sysbot+tracker@w3.org on 2010-07-15)

Related notes:

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
