BufferPoint

View bound to the underlying buffer data of a BufferPointCollection.

BufferPoint instances are flyweights: a single BufferPoint instance can be temporarily bound to any conceptual "point" in a BufferPointCollection, allowing very large collections to be iterated and updated with a minimal memory footprint.

Represented as one (1) position.
