template<typename>
class Enlighten::GenericColourBuffer

Generic class to store an array of values for a given system.

The type of values stored is determined by the 'C' template parameter. Unlike the IncidentLightingBuffer and InputLightingBuffer, this class does not support run-time selection of format precision. This class requires that the 'C' type define an ExpandedType. This allows having a compressed format that expands to a v128 or possibly just a single float. The compressed format is expanded on read and compressed on write although that logic belongs in the 'C' object.
