Volumetric fog denoising mode "Gaussian" adds square artifacts.

HD RP

-

With certain fog setup, the volumetric denoising option "Gaussian" reduces the quality of the fog by adding filtering artifacts in the fog.

Repro steps:
- Open the scene "VolumetricFilterIssue" scene in the package attached
- Set the camera to look at an edge of the fog with a scale of 5x in the game view to view more clearly the issue.
- Toggle the denoising mode between "Gaussian" and None and observe changes in the scene view
- When using Gaussian, we can see square artifacts in the fog.

  1. Resolution Note:

    When Gaussian is enabled, fetching from V-Buffer has "quadratic construction" disabled (in AtmosphericScattering.hlsl, line 280). This is because the quadratic construction is quite expensive doing 4x 3D texture fetches upon V-Buffer sampling and we don't want the added overhead on top of the Gaussian filter.
