Each sample as computed when sampling the indirect illumination.
The RayHemiSample is the point on the RayHemisphere used for computing the indirect illumination when caches are used.
Contains all the information needed to compute the gradients for GI. When gradients are used these values should be used to compute the indirect illumination.
