/**
 * @typedef {object} ArcGisMapServerImageryProvider.ConstructorOptions
 *
 * Initialization options for the ArcGisMapServerImageryProvider constructor
 *
 * @property {Resource|string} [url] The URL of the ArcGIS MapServer service. Deprecated.
 * @property {string} [token] The ArcGIS token used to authenticate with the ArcGIS MapServer service. Deprecated.
 * @property {TileDiscardPolicy} [tileDiscardPolicy] The policy that determines if a tile
 *        is invalid and should be discarded.  If this value is not specified, a default
 *        {@link DiscardMissingTileImagePolicy} is used for tiled map servers, and a
 *        {@link NeverTileDiscardPolicy} is used for non-tiled map servers.  In the former case,
 *        we request tile 0,0 at the maximum tile level and check pixels (0,0), (200,20), (20,200),
 *        (80,110), and (160, 130).  If all of these pixels are transparent, the discard check is
 *        disabled and no tiles are discarded.  If any of them have a non-transparent color, any
 *        tile that has the same values in these pixel locations is discarded.  The end result of
 *        these defaults should be correct tile discarding for a standard ArcGIS Server.  To ensure
 *        that no tiles are discarded, construct and pass a {@link NeverTileDiscardPolicy} for this
 *        parameter.
 * @property {boolean} [usePreCachedTilesIfAvailable=true] If true, the server's pre-cached
 *        tiles are used if they are available. Exporting Tiles is only supported with deprecated APIs.
 * @property {string} [layers] A comma-separated list of the layers to show, or undefined if all layers should be shown.
 * @property {boolean} [enablePickFeatures=true] If true, {@link ArcGisMapServerImageryProvider#pickFeatures} will invoke
 *        the Identify service on the MapServer and return the features included in the response.  If false,
 *        {@link ArcGisMapServerImageryProvider#pickFeatures} will immediately return undefined (indicating no pickable features)
 *        without communicating with the server.  Set this property to false if you don't want this provider's features to
 *        be pickable. Can be overridden by setting the {@link ArcGisMapServerImageryProvider#enablePickFeatures} property on the object.
 * @property {Rectangle} [rectangle=Rectangle.MAX_VALUE] The rectangle of the layer.  This parameter is ignored when accessing
 *                    a tiled layer.
 * @property {TilingScheme} [tilingScheme=new GeographicTilingScheme()] The tiling scheme to use to divide the world into tiles.
 *                       This parameter is ignored when accessing a tiled server.
 * @property {Ellipsoid} [ellipsoid] The ellipsoid.  If the tilingScheme is specified and used,
 *                    this parameter is ignored and the tiling scheme's ellipsoid is used instead. If neither
 *                    parameter is specified, the WGS84 ellipsoid is used.
 * @property {Credit|string} [credit] A credit for the data source, which is displayed on the canvas.  This parameter is ignored when accessing a tiled server.
 * @property {number} [tileWidth=256] The width of each tile in pixels.  This parameter is ignored when accessing a tiled server.
 * @property {number} [tileHeight=256] The height of each tile in pixels.  This parameter is ignored when accessing a tiled server.
 * @property {number} [maximumLevel] The maximum tile level to request, or undefined if there is no maximum.  This parameter is ignored when accessing
 *                                        a tiled server.
