class Enlighten::IncidentLightingBuffer
A buffer containing the incident lighting for a system's input sample points (internal).
Runtime data allocated by end user that stores incident lighting from a set of lights for each cluster.
E.g. leaf clusters or "input lighting" cube map samples. It would not typically include bounce or albedo. Implemented as straight forward set of lighting values, but can operate at two different precisions.
