> > This uses a new method of blurring that runs the three
> > passes of the box filter in a single pass. This implementation
> > currently only does 1x1 pixel at a time, but it should be simple
> > to expand to 4x4 pixels at a time.

> > On the  blur_10_normal_high_quality benchmark, the new is 7% faster
> > than the old code. For the blur_100.50_normal_high_quality
> > benchmark, the new code is 11% slower.
