Detailed Description

Computes the near field blur.

This is included by both the horizontal (first) and vertical (second) passes.

The shader produces two outputs:

blurResult

A buffer that is the scene blurred with a spatially varying kernel kernel that attempts to make the point-spread function at each pixel equal to its circle of confusion radius.

blurResult.rgb = color blurResult.a = normalized coc radius

nearResult

A buffer that contains only near field, blurred with premultiplied alpha. The point spread function is a fixed RADIUS in this region.

nearResult.rgb = coverage * color nearResult.a = coverage
