Herbert Derby 5e18cdea0a Direct evaluation of gaussian
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
temporary memory buffer.
