-		Compute the draw offset for large models by chunking the index buffer into chunks of 65k addressable vertices.
-		This method will effectively rewrite the index buffer and remap all attributes to match the new indices.
-		WARNING: This method will also expand the vertex count to prevent sprawled triangles across draw offsets.
-		size - Defaults to 65535 or 4294967296 if extension OES_element_index_uint supported, but allows for larger or smaller chunks.
