Experimental blur code.
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.
