/**

* @property {module:ol/extent~Extent} [extent] Extent for the tile grid. The origin for an XYZ tile grid is the
* top-left corner of the extent. The zero level of the grid is defined by the resolution at which one tile fits in the
* provided extent. If not provided, the extent of the EPSG:3857 projection is used.
* @property {number} [maxZoom] Maximum zoom. The default is `ol.DEFAULT_MAX_ZOOM`. This determines the number of levels
* in the grid set. For example, a `maxZoom` of 21 means there are 22 levels in the grid set.
* @property {number} [minZoom=0] Minimum zoom.
* @property {number|module:ol/size~Size} [tileSize=[256, 256]] Tile size in pixels.
