When denoising tiles the intensity of the entire image should be computed, i.e. 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).
