Detailed Description

Compute areashadow for a grid. Unlike other Rix interfaces, RixAreaShadow is a thin layer on top of an underlying RSL shadeop, areashadow(). The array of filter regions or surface points must be the same size as the implicit grid.

On the other hand, the number of light samples is unconstrained. Light samples are points on the light (as opposed to directions). The RSL optional outputs perRayTransmission, perRayL, perRayLLength are mandatory here, but result is not. If not needed, pass a null pointer to result.
