[Bug 9942] The sentence "The shadowBlur attribute specifies the size of the blurring effect." is misleading, It should say "The shadowBlur attribute specifies the level of the blurring effect."

Not sure if this is the proper place to point out this, anyway it seems
interesting information. After this time I've checked the 3 specifications
related with shadows and blurs:

   - SVG ->
http://www.w3.org/TR/SVG/filters.html#feGaussianBlurStdDeviationAttribute
   - HTML5 canvas shadows ->
http://www.whatwg.org/specs/web-apps/current-work/#shadows
   - CSS3 -> http://www.w3.org/TR/css3-background/#the-box-shadow

Considering all of them are going to be implemented in the same application
(the web engines) and that probably we can consider them part of the same API,
having different parameters seems confusing: some of them use the blur radius
and do not recomend blur algorithm and others use the standard deviation and
even recommend a way to do it.

I hope this helps :).
