 * @deprecated Use [`tosijs-3d`](https://www.npmjs.com/package/tosijs-3d) instead.

 * It is a much better library, and maintaining both is duplicated effort spent against
 * the weaker one. This is a thin Babylon wrapper that grew inside a general-purpose UI
 * library; `tosijs-3d` is a project actually about 3D and XR, and `tosijs-3d` grew out of
 * this component, so migration is mostly a rename.
 *
 * Still exported and still works. It will be removed in a future major.
