  /**
   * The `Map` object represents the map on your page. It exposes methods
   * and properties that enable you to programmatically change the map,
   * and fires events as users interact with it.
   *
   * You create a `Map` by specifying a `container` and other options.
   * Then Mapbox GL JS initializes the map on the page and returns your `Map`
   * object.
   *
   * @extends Evented
   * @param {Object} options
   * @param {HTMLElement|string} options.container The HTML element in which Mapbox GL JS will render the map, or the element's string `id`. The specified element must have no children.
   * @param {number} [options.minZoom=0] The minimum zoom level of the map (0-24).
   * @param {number} [options.maxZoom=22] The maximum zoom level of the map (0-24).
   * @param {number} [options.minPitch=0] The minimum pitch of the map (0-60).
   * @param {number} [options.maxPitch=60] The maximum pitch of the map (0-60).
   * @param {Object|string} [options.style] The map's Mapbox style. This must be an a JSON object conforming to
   * the schema described in the [Mapbox Style Specification](https://mapbox.com/mapbox-gl-style-spec/), or a URL to
   * such JSON.
   *
   * To load a style from the Mapbox API, you can use a URL of the form `mapbox://styles/:owner/:style`,
   * where `:owner` is your Mapbox account name and `:style` is the style ID. Or you can use one of the following
   * [the predefined Mapbox styles](https://www.mapbox.com/maps/):
   *
   *  * `mapbox://styles/mapbox/streets-v11`
   *  * `mapbox://styles/mapbox/outdoors-v11`
   *  * `mapbox://styles/mapbox/light-v10`
   *  * `mapbox://styles/mapbox/dark-v10`
   *  * `mapbox://styles/mapbox/satellite-v9`
   *  * `mapbox://styles/mapbox/satellite-streets-v11`
   *  * `mapbox://styles/mapbox/navigation-preview-day-v4`
   *  * `mapbox://styles/mapbox/navigation-preview-night-v4`
   *  * `mapbox://styles/mapbox/navigation-guidance-day-v4`
   *  * `mapbox://styles/mapbox/navigation-guidance-night-v4`
   *
   * Tilesets hosted with Mapbox can be style-optimized if you append `?optimize=true` to the end of your style URL, like `mapbox://styles/mapbox/streets-v11?optimize=true`.
   * Learn more about style-optimized vector tiles in our [API documentation](https://www.mapbox.com/api-documentation/maps/#retrieve-tiles).
   *
   * @param {(boolean|string)} [options.hash=false] If `true`, the map's position (zoom, center latitude, center longitude, bearing, and pitch) will be synced with the hash fragment of the page's URL.
   *   For example, `http://path/to/my/page.html#2.59/39.26/53.07/-24.1/60`.
   *   An additional string may optionally be provided to indicate a parameter-styled hash,
   *   e.g. http://path/to/my/page.html#map=2.59/39.26/53.07/-24.1/60&foo=bar, where foo
   *   is a custom parameter and bar is an arbitrary hash distinct from the map hash.
   * @param {boolean} [options.interactive=true] If `false`, no mouse, touch, or keyboard listeners will be attached to the map, so it will not respond to interaction.
   * @param {number} [options.bearingSnap=7] The threshold, measured in degrees, that determines when the map's
   *   bearing will snap to north. For example, with a `bearingSnap` of 7, if the user rotates
   *   the map within 7 degrees of north, the map will automatically snap to exact north.
   * @param {boolean} [options.pitchWithRotate=true] If `false`, the map's pitch (tilt) control with "drag to rotate" interaction will be disabled.
   * @param {number} [options.clickTolerance=3] The max number of pixels a user can shift the mouse pointer during a click for it to be considered a valid click (as opposed to a mouse drag).
   * @param {boolean} [options.attributionControl=true] If `true`, an {@link AttributionControl} will be added to the map.
   * @param {string | Array<string>} [options.customAttribution] String or strings to show in an {@link AttributionControl}. Only applicable if `options.attributionControl` is `true`.
   * @param {string} [options.logoPosition='bottom-left'] A string representing the position of the Mapbox wordmark on the map. Valid options are `top-left`,`top-right`, `bottom-left`, `bottom-right`.
   * @param {boolean} [options.failIfMajorPerformanceCaveat=false] If `true`, map creation will fail if the performance of Mapbox
   *   GL JS would be dramatically worse than expected (i.e. a software renderer would be used).
   * @param {boolean} [options.preserveDrawingBuffer=false] If `true`, the map's canvas can be exported to a PNG using `map.getCanvas().toDataURL()`. This is `false` by default as a performance optimization.
   * @param {boolean} [options.antialias] If `true`, the gl context will be created with MSAA antialiasing, which can be useful for antialiasing custom layers. this is `false` by default as a performance optimization.
   * @param {boolean} [options.refreshExpiredTiles=true] If `false`, the map won't attempt to re-request tiles once they expire per their HTTP `cacheControl`/`expires` headers.
   * @param {LngLatBoundsLike} [options.maxBounds] If set, the map will be constrained to the given bounds.
   * @param {boolean|Object} [options.scrollZoom=true] If `true`, the "scroll to zoom" interaction is enabled. An `Object` value is passed as options to {@link ScrollZoomHandler#enable}.
   * @param {boolean} [options.boxZoom=true] If `true`, the "box zoom" interaction is enabled (see {@link BoxZoomHandler}).
   * @param {boolean} [options.dragRotate=true] If `true`, the "drag to rotate" interaction is enabled (see {@link DragRotateHandler}).
   * @param {boolean|Object} [options.dragPan=true] If `true`, the "drag to pan" interaction is enabled. An `Object` value is passed as options to {@link DragPanHandler#enable}.
   * @param {boolean} [options.keyboard=true] If `true`, keyboard shortcuts are enabled (see {@link KeyboardHandler}).
   * @param {boolean} [options.doubleClickZoom=true] If `true`, the "double click to zoom" interaction is enabled (see {@link DoubleClickZoomHandler}).
   * @param {boolean|Object} [options.touchZoomRotate=true] If `true`, the "pinch to rotate and zoom" interaction is enabled. An `Object` value is passed as options to {@link TouchZoomRotateHandler#enable}.
   * @param {boolean|Object} [options.touchPitch=true] If `true`, the "drag to pitch" interaction is enabled. An `Object` value is passed as options to {@link TouchPitchHandler#enable}.
   * @param {boolean} [options.trackResize=true]  If `true`, the map will automatically resize when the browser window resizes.
   * @param {LngLatLike} [options.center=[0, 0]] The inital geographical centerpoint of the map. If `center` is not specified in the constructor options, Mapbox GL JS will look for it in the map's style object. If it is not specified in the style, either, it will default to `[0, 0]` Note: Mapbox GL uses longitude, latitude coordinate order (as opposed to latitude, longitude) to match GeoJSON.
   * @param {number} [options.zoom=0] The initial zoom level of the map. If `zoom` is not specified in the constructor options, Mapbox GL JS will look for it in the map's style object. If it is not specified in the style, either, it will default to `0`.
   * @param {number} [options.bearing=0] The initial bearing (rotation) of the map, measured in degrees counter-clockwise from north. If `bearing` is not specified in the constructor options, Mapbox GL JS will look for it in the map's style object. If it is not specified in the style, either, it will default to `0`.
   * @param {number} [options.pitch=0] The initial pitch (tilt) of the map, measured in degrees away from the plane of the screen (0-60). If `pitch` is not specified in the constructor options, Mapbox GL JS will look for it in the map's style object. If it is not specified in the style, either, it will default to `0`.
   * @param {LngLatBoundsLike} [options.bounds] The initial bounds of the map. If `bounds` is specified, it overrides `center` and `zoom` constructor options.
   * @param {Object} [options.fitBoundsOptions] A {@link Map#fitBounds} options object to use _only_ when fitting the initial `bounds` provided above.
   * @param {boolean} [options.renderWorldCopies=true]  If `true`, multiple copies of the world will be rendered side by side beyond -180 and 180 degrees longitude. If set to `false`:
   * - When the map is zoomed out far enough that a single representation of the world does not fill the map's entire
   * container, there will be blank space beyond 180 and -180 degrees longitude.
   * - Features that cross 180 and -180 degrees longitude will be cut in two (with one portion on the right edge of the
   * map and the other on the left edge of the map) at every zoom level.
   * @param {number} [options.maxTileCacheSize=null]  The maximum number of tiles stored in the tile cache for a given source. If omitted, the cache will be dynamically sized based on the current viewport.
   * @param {string} [options.localIdeographFontFamily='sans-serif'] Defines a CSS
   *   font-family for locally overriding generation of glyphs in the 'CJK Unified Ideographs', 'Hiragana', 'Katakana' and 'Hangul Syllables' ranges.
   *   In these ranges, font settings from the map's style will be ignored, except for font-weight keywords (light/regular/medium/bold).
   *   Set to `false`, to enable font settings from the map's style for these glyph ranges.  Note that [Mapbox Studio](https://studio.mapbox.com/) sets this value to `false` by default.
   *   The purpose of this option is to avoid bandwidth-intensive glyph server requests. (See [Use locally generated ideographs](https://www.mapbox.com/mapbox-gl-js/example/local-ideographs).)
   * @param {RequestTransformFunction} [options.transformRequest=null] A callback run before the Map makes a request for an external URL. The callback can be used to modify the url, set headers, or set the credentials property for cross-origin requests.
   *   Expected to return an object with a `url` property and optionally `headers` and `credentials` properties.
   * @param {boolean} [options.collectResourceTiming=false] If `true`, Resource Timing API information will be collected for requests made by GeoJSON and Vector Tile web workers (this information is normally inaccessible from the main Javascript thread). Information will be returned in a `resourceTiming` property of relevant `data` events.
   * @param {number} [options.fadeDuration=300] Controls the duration of the fade-in/fade-out animation for label collisions, in milliseconds. This setting affects all symbol layers. This setting does not affect the duration of runtime styling transitions or raster tile cross-fading.
   * @param {boolean} [options.crossSourceCollisions=true] If `true`, symbols from multiple sources can collide with each other during collision detection. If `false`, collision detection is run separately for the symbols in each source.
   * @param {string} [options.accessToken=null] If specified, map will use this token instead of the one defined in mapboxgl.accessToken.
   * @param {Object} [options.locale=null] A patch to apply to the default localization table for UI strings, e.g. control tooltips. The `locale` object maps namespaced UI string IDs to translated strings in the target language; see `src/ui/default_locale.js` for an example with all supported string IDs. The object may specify all UI strings (thereby adding support for a new translation) or only a subset of strings (thereby patching the default translation table).
   * @example
   * var map = new mapboxgl.Map({
   *   container: 'map',
   *   center: [-122.420679, 37.772537],
   *   zoom: 13,
   *   style: style_object,
   *   hash: true,
   *   transformRequest: (url, resourceType)=> {
   *     if(resourceType === 'Source' && url.startsWith('http://myHost')) {
   *       return {
   *        url: url.replace('http', 'https'),
   *        headers: { 'my-custom-header': true},
   *        credentials: 'include'  // Include cookies for cross-origin requests
   *      }
   *     }
   *   }
   * });

       * contribution to the rendered result; for example, because the layer's opacity or color alpha component is set to
       * 0.
       *
       * The topmost rendered feature appears first in the returned array, and subsequent features are sorted by
       * descending z-order. Features that are rendered multiple times (due to wrapping across the antimeridian at low
       * zoom levels) are returned only once (though subject to the following caveat).
       *
       * Because features come from tiled vector data or GeoJSON data that is converted to tiles internally, feature
       * geometries may be split or duplicated across tile boundaries and, as a result, features may appear multiple
       * times in query results. For example, suppose there is a highway running through the bounding rectangle of a query.
       * The results of the query will be those parts of the highway that lie within the map tiles covering the bounding
       * rectangle, even if the highway extends into other tiles, and the portion of the highway within each map tile
       * will be returned as a separate feature. Similarly, a point feature near a tile boundary may appear in multiple
       * tiles due to tile buffering.
       *
       * @example
       * // Find all features at a point
       * var features = map.queryRenderedFeatures(
       *   [20, 35],
       *   { layers: ['my-layer-name'] }
       * );
       *
       * @example
       * // Find all features within a static bounding box
       * var features = map.queryRenderedFeatures(
       *   [[10, 20], [30, 50]],
       *   { layers: ['my-layer-name'] }
       * );
       *
       * @example
       * // Find all features within a bounding box around a point
       * var width = 10;
       * var height = 20;
       * var features = map.queryRenderedFeatures([
       *   [point.x - width / 2, point.y - height / 2],
       *   [point.x + width / 2, point.y + height / 2]
       * ], { layers: ['my-layer-name'] });
       *
       * @example
       * // Query all rendered features from a single layer
       * var features = map.queryRenderedFeatures({ layers: ['my-layer-name'] });

If you change feature data using `map.getSource('some id').setData(..)`, you may need to re-apply state taking into account updated `id` values.
