           Summary: [BlackBerry][CSS Filters] Blur filter fails to

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
