Historically, Blink's blur-radius interpretation has been at odds with both the CSS and Canvas2D specs: Blink shadows cover about half the expected area (see linked bug). With this change Gaussian blur sigma is now computed as 1/2 blur-radius, as mandated by spec. Blink's shadow implementation now matches FireFox and Safari.

The main purpose of this CPS entry is to trickle out into release notes, in order to minimize the surprise factor associated with a user-visible change in blur-radius interpretation.
