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.

| Name | Description |
|---|---|
| CalculateBufferSize(Geo::s32, PrecisionHint::Value) | Factory Methods. |
| Clear() | Clears this buffer to all zeroes. |

| Copy(const IncidentLightingBuffer &) | Copy the contents of the given buffer into this one. |
| Create(Geo::GeoGuid, Geo::s32, void *, PrecisionHint::Value) | Factory Methods. |
| Create(const IncidentLightingBuffer &, void *) | Factory Methods. |
| GetLastSkipHash() | A hash of the lights before they have been sorted. |
| GetLightValues() | Return a pointer to the light values. |
| GetLightValues() | Return a const pointer to the light values. |
| GetNumLightValues() | Return the number of light values. |

| GetPrecision() | Gets the precision. |
| GetSize() | Gets the total size (in bytes) of this buffer. |
| GetSystemId() | Return the system guid for this IncidentLightingBuffer. |
| WasLastUpdateSkipped() | returns true if the last update of the IncidentLightingBuffer was skipped due to the input lights being unchanged. |
