This is useful for denoising HDR images which are very dark or bright. The returned value 'outputIntensity' is multiplied with the RGB values of the input image/tile in optixDenoiserInvoke if given in the parameter OptixDenoiserParams::hdrIntensity (otherwise 'hdrIntensity' must be a null pointer).
