This is the same technique the old "InstancedGeometry" implementation used (with improvements).
Defines a part of a complete mesh.

InstanceBatch forms part of the new Instancing system This is an abstract class that must be derived ...
Summary class collecting together vertex source information.
'New' rendering operation using vertex buffers.
This is the main starting point for the new instancing system.
