nCine::GLHashMap class

Naive fixed-size hashmap of OpenGL targets to object ids.

Stores one object id per bucket, where MappingFunc maps an OpenGL target (the key) to a bucket index. Used to cache the currently bound object id for each target. The number of buckets S must match the range of the mapping function.
