   * contain the geometry of the TiledGeometryLayer. It is usually a
   * `THREE.Group`, but it can be anything inheriting from a `THREE.Object3d`.

   * will be merged as is in the layer. For example, if the configuration
   * contains three elements `name, protocol, extent`, these elements will be
   * available using `layer.name` or something else depending on the property
   * name.
   * @param {number} [config.maxSubdivisionLevel=5] - Maximum subdivision
   * level for this tiled layer.
   * @param {number} [config.maxDeltaElevationLevel=4] - Maximum delta between
   * two elevations tile.
   *
   * @throws {Error} `object3d` must be a valid `THREE.Object3d`.
