enablePickFeatures
Gets or sets a value indicating whether feature picking is enabled. If true, WebMapServiceImageryProvider.pickFeatures will invoke the GetFeatureInfo service on the WMS server and attempt to interpret the features included in the response. If false, WebMapServiceImageryProvider.pickFeatures will immediately return undefined (indicating no pickable features) without communicating with the server. Set this property to false if you know your data source does not support picking features or if you don't want this provider's features to be pickable.
