Original change's description:
> Experimental blur code with 32 bit fix.
> 
> 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.
>
