* PartialMeshBuffer
*
* Attach alternate `Indices` to an existing mesh buffer, to make it possible to use different
* indices with the same vertex buffer.
*
* Irrlicht does not currently support this: `CMeshBuffer` ties together a single vertex buffer
* and a single index buffer. There's no way to share these between mesh buffers.
