Now that we've extracted all of the stateless functions that can be hidden, it's time to make the index generator a regular class with active data members. This can just be a member that sits within the vertex manager base class. By deglobalizing the state of the index generator we also get rid of the wonky dual-initializing that was going on within the OpenGL backend. Since the renderer is always initialized before the vertex manager, we now only call Init() once throughout the execution lifecycle.
