 *
 * Initialization options for the WebMapServiceImageryProvider constructor
 *
 * @property {Resource|string} url The URL of the WMS service. The URL supports the same keywords as the {@link UrlTemplateImageryProvider}.
 * @property {string} layers The layers to include, separated by commas.
 * @property {object} [parameters=WebMapServiceImageryProvider.DefaultParameters] Additional parameters to pass to the WMS server in the GetMap URL.
 * @property {object} [getFeatureInfoParameters=WebMapServiceImageryProvider.GetFeatureInfoDefaultParameters] Additional parameters to pass to the WMS server in the GetFeatureInfo URL.
 * @property {boolean} [enablePickFeatures=true] If true, {@link WebMapServiceImageryProvider#pickFeatures} will invoke
 *        the GetFeatureInfo operation on the WMS server and return the features included in the response.  If false,
 *        {@link WebMapServiceImageryProvider#pickFeatures} will immediately return undefined (indicating no pickable features)
 *        without communicating with the server.  Set this property to false if you know your WMS server does not support
 *        GetFeatureInfo or if you don't want this provider's features to be pickable. Note that this can be dynamically
 *        overridden by modifying the WebMapServiceImageryProvider#enablePickFeatures property.

 *        in which to try WMS GetFeatureInfo requests.
 * @property {Rectangle} [rectangle=Rectangle.MAX_VALUE] The rectangle of the layer.
 * @property {TilingScheme} [tilingScheme=new GeographicTilingScheme()] The tiling scheme to use to divide the world into tiles.
 * @property {Ellipsoid} [ellipsoid] The ellipsoid.  If the tilingScheme is specified,
 *        this parameter is ignored and the tiling scheme's ellipsoid is used instead. If neither
 *        parameter is specified, the WGS84 ellipsoid is used.
 * @property {number} [tileWidth=256] The width of each tile in pixels.
 * @property {number} [tileHeight=256] The height of each tile in pixels.
 * @property {number} [minimumLevel=0] The minimum level-of-detail supported by the imagery provider.  Take care when
 *        specifying this that the number of tiles at the minimum level is small, such as four or less.  A larger number is
 *        likely to result in rendering problems.
 * @property {number} [maximumLevel] The maximum level-of-detail supported by the imagery provider, or undefined if there is no limit.
 *        If not specified, there is no limit.
 * @property {string} [crs] CRS specification, for use with WMS specification >= 1.3.0.
 * @property {string} [srs] SRS specification, for use with WMS specification 1.1.0 or 1.1.1
 * @property {Credit|string} [credit] A credit for the data source, which is displayed on the canvas.
 * @property {string|string[]} [subdomains='abc'] The subdomains to use for the <code>{s}</code> placeholder in the URL template.
 *                          If this parameter is a single string, each character in the string is a subdomain.  If it is
 *                          an array, each element in the array is a subdomain.
 * @property {Clock} [clock] A Clock instance that is used when determining the value for the time dimension. Required when `times` is specified.
 * @property {TimeIntervalCollection} [times] TimeIntervalCollection with its data property being an object containing time dynamic dimension and their values.
 * @property {Resource|string} [getFeatureInfoUrl] The getFeatureInfo URL of the WMS service. If the property is not defined then we use the property value of url.
