Fix T93029: OptiX denoising artifacts at high sample counts in specific scenes
Partially reverts commit rB440a3475b8f5410e5c41bfbed5ce82771b41356f because
"optixDenoiserComputeIntensity" does not currently support input images that are not packed (the
"pixelStrideInBytes" field is not zero). As a result the intensity calculation would take into account
data from other passes in the image, some of which was scaled by the number of samples still and
therefore produce widely incorrect results that then caused artifacts in the denoised image.
Maniphest Tasks: T93029
