Improved raster blur implementation.
We use more bits of precision in the fixed point exponential blur
algorithm, which allows more fine-grained radii which is required for
animating the blur. Also optimize the implementation a bit by
transposing the image instead of blurring vertically which isn't very
cache-efficient.
