createBlurStage

Creates a post-process stage that applies a Gaussian blur to the input texture. This stage is usually applied in conjunction with another stage.

This stage has the following uniforms: delta, sigma, and stepSize.

delta and sigma are used to compute the weights of a Gaussian filter. The equation is exp((-0.5 * delta * delta) / (sigma * sigma)). The default value for delta is 1.0. The default value for sigma is 2.0. stepSize is the distance to the next texel. The default is 1.0.
