> > The SVG(CSS) standard allows the 3 pass algorithm for sigma >= 2. But
> > sigma < 2, the code must evaluate to the convolution. The old code used
> > an interpolation scheme between windowed filters. This code directly
> > evaluates the gaussian kernel for sigma < 2.

> > This code produces cleaner results, is 25% faster, and does not use a
