* @param {Object} [config] - Optional configuration, all elements in it
* 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.minSubdivisionLevel=2] - Minimum subdivision
* level for this tiled layer.

* level for this tiled layer.
* @param {number} [config.sseSubdivisionThreshold=1] - Threshold level for
