Description Arvid Nilsson 2013-04-09 06:00:52 PDT 
This seems to happen frequently with CSS filters applied to images - the initial
image size is small, and when the image is fully decoded the surface size
increases to the true image size.

If a surface starts out at 12x12, the blur distance will be computed as 1/12
and that will still be used when the surface increases to the right size.

Can be seen by manual inspection ofLayoutTests/css3/filters/effect-blur-hw.html

"blur size" is the term used in the actual shader
