-/**
- * @classdesc
- * An ol.View object represents a simple 2D view of the map.
- *
- * This is the object to act upon to change the center, resolution,
- * and rotation of the map.
- *
- * ### The view states
- *
- * An `ol.View` is determined by three states: `center`, `resolution`,
- * and `rotation`. Each state has a corresponding getter and setter, e.g.
- * `getCenter` and `setCenter` for the `center` state.
- *
- * An `ol.View` has a `projection`. The projection determines the
- * coordinate system of the center, and its units determine the units of the
- * resolution (projection units per pixel). The default projection is
- * Spherical Mercator (EPSG:3857).
- *
- * ### The constraints
- *
- * `setCenter`, `setResolution` and `setRotation` can be used to change the
- * states of the view. Any value can be passed to the setters. And the value
- * that is passed to a setter will effectively be the value set in the view,
- * and returned by the corresponding getter.
- *
- * But an `ol.View` object also has a *resolution constraint*, a
- * *rotation constraint* and a *center constraint*.
- *
- * As said above, no constraints are applied when the setters are used to set
- * new states for the view. Applying constraints is done explicitly through
- * the use of the `constrain*` functions (`constrainResolution` and
- * `constrainRotation` and `constrainCenter`).
- *
- * The main users of the constraints are the interactions and the
- * controls. For example, double-clicking on the map changes the view to
- * the "next" resolution. And releasing the fingers after pinch-zooming
- * snaps to the closest resolution (with an animation).
- *
- * The *resolution constraint* snaps to specific resolutions. It is
- * determined by the following options: `resolutions`, `maxResolution`,
- * `maxZoom`, and `zoomFactor`. If `resolutions` is set, the other three
- * options are ignored. See documentation for each option for more
- * information.
- *
- * The *rotation constraint* snaps to specific angles. It is determined
- * by the following options: `enableRotation` and `constrainRotation`.
- * By default the rotation value is snapped to zero when approaching the
- * horizontal.
- *
- * The *center constraint* is determined by the `extent` option. By
- * default the center is not constrained at all.
- *

- * @extends {ol.Object}

- * A control is a visible widget with a DOM element in a fixed position on the

- * container with CSS class name `ol-overlaycontainer-stopevent`, but can use
- * any outside DOM element.
- *
- * This is the base class for controls. You can use it for simple custom
- * controls by creating the element with listeners, creating an instance:
- * ```js
- * var myControl = new ol.control.Control({element: myElement});
- * ```
- * and then adding this to the map.
- *
- * The main advantage of having this as a control rather than a simple separate
- * DOM element is that preventing propagation is handled for you. Controls
- * will also be `ol.Object`s in a `ol.Collection`, so you can use their
- * methods.

- * You can also extend this base for your own control class. See

-/**
- * @classdesc
- * The map is the core component of OpenLayers. For a map to render, a view,
- * one or more layers, and a target container are needed:
- *
- * var map = new ol.CanvasMap({
- * view: new ol.View({
- * center: [0, 0],
- * zoom: 1
- * }),
- * layers: [
- * new ol.layer.Tile({
- * source: new ol.source.OSM()
- * })
- * ],
- * target: 'map'
- * });
- *
- * The above snippet creates a map using a {@link ol.layer.Tile} to display
- * {@link ol.source.OSM} OSM data and render it to a DOM element with the
- * id `map`.
- *
- * The constructor places a viewport container (with CSS class name
- * `ol-viewport`) in the target element (see `getViewport()`), and then two
- * further elements within the viewport: one with CSS class name
- * `ol-overlaycontainer-stopevent` for controls and some overlays, and one with
- * CSS class name `ol-overlaycontainer` for other overlays (see the `stopEvent`
- * option of {@link ol.Overlay} for the difference). The map itself is placed in
- * a further element within the viewport.
- *
- * Layers are stored as a `ol.Collection` in layerGroups. A top-level group is
- * provided by the library. This is what is accessed by `getLayerGroup` and
- * `setLayerGroup`. Layers entered in the options are added to this group, and
- * `addLayer` and `removeLayer` change the layer collection in the group.
- * `getLayers` is a convenience function for `getLayerGroup().getLayers()`.
- * Note that `ol.layer.Group` is a subclass of `ol.layer.Base`, so layers
- * entered in the options or added with `addLayer` can be groups, which can
- * contain further groups, and so on.
- *
- * @constructor
- * @extends {ol.PluggableMap}

-/**
- * @classdesc
- * The ol.DeviceOrientation class provides access to information from
- * DeviceOrientation events. See the [HTML 5 DeviceOrientation Specification](
- * http://www.w3.org/TR/orientation-event/) for more details.
- *
- * Many new computers, and especially mobile phones
- * and tablets, provide hardware support for device orientation. Web
- * developers targeting mobile devices will be especially interested in this
- * class.
- *
- * Device orientation data are relative to a common starting point. For mobile
- * devices, the starting point is to lay your phone face up on a table with the
- * top of the phone pointing north. This represents the zero state. All
- * angles are then relative to this state. For computers, it is the same except
- * the screen is open at 90 degrees.
- *
- * Device orientation is reported as three angles - `alpha`, `beta`, and
- * `gamma` - relative to the starting position along the three planar axes X, Y
- * and Z. The X axis runs from the left edge to the right edge through the
- * middle of the device. Similarly, the Y axis runs from the bottom to the top
- * of the device through the middle. The Z axis runs from the back to the front
- * through the middle. In the starting position, the X axis points to the
- * right, the Y axis points away from you and the Z axis points straight up
- * from the device lying flat.
- *
- * The three angles representing the device orientation are relative to the
- * three axes. `alpha` indicates how much the device has been rotated around the
- * Z axis, which is commonly interpreted as the compass heading (see note
- * below). `beta` indicates how much the device has been rotated around the X
- * axis, or how much it is tilted from front to back. `gamma` indicates how
- * much the device has been rotated around the Y axis, or how much it is tilted
- * from left to right.
- *
- * For most browsers, the `alpha` value returns the compass heading so if the
- * device points north, it will be 0. With Safari on iOS, the 0 value of
- * `alpha` is calculated from when device orientation was first requested.
- * ol.DeviceOrientation provides the `heading` property which normalizes this
- * behavior across all browsers for you.
- *
- * It is important to note that the HTML 5 DeviceOrientation specification
- * indicates that `alpha`, `beta` and `gamma` are in degrees while the
- * equivalent properties in ol.DeviceOrientation are in radians for consistency
- * with all other uses of angles throughout OpenLayers.
- *
- * To get notified of device orientation changes, register a listener for the
- * generic `change` event on your `ol.DeviceOrientation` instance.
- *
- * @see {@link http://www.w3.org/TR/orientation-event/}

- * @classdesc
- * A vector object for geographic features with a geometry and other
- * attribute properties, similar to the features in vector file formats like
- * GeoJSON.
- *
- * Features can be styled individually with `setStyle`; otherwise they use the
- * style of their vector layer.
- *
- * Note that attribute properties are set as {@link ol.Object} properties on
- * the feature object, so they are observable, and have get/set accessors.
- *
- * Typically, a feature has a single geometry property. You can set the
- * geometry using the `setGeometry` method and get it with `getGeometry`.
- * It is possible to store more than one geometry on a feature using attribute
- * properties. By default, the geometry used for rendering is identified by
- * the property name `geometry`. If you want to use another geometry property
- * for rendering, use the `setGeometryName` method to change the attribute
- * property associated with the geometry for the feature. For example:
- *
- * ```js
- * var feature = new ol.Feature({
- * geometry: new ol.geom.Polygon(polyCoords),
- * labelPoint: new ol.geom.Point(labelCoords),
- * name: 'My Polygon'
- * });
- *
- * // get the polygon geometry
- * var poly = feature.getGeometry();
- *
- * // Render the feature as a point using the coordinates from labelPoint
- * feature.setGeometryName('labelPoint');
- *
- * // get the point geometry
- * var point = feature.getGeometry();
- * ```
- *
- * @constructor
- * @extends {ol.Object}
- * @param {ol.geom.Geometry|Object.<string, *>=} opt_geometryOrProperties
- * You may pass a Geometry object directly, or an object literal
- * containing properties. If you pass an object literal, you may
- * include a Geometry associated with a `geometry` key.

- * @classdesc
- * The map is the core component of OpenLayers. For a map to render, a view,
- * one or more layers, and a target container are needed:
- *
- * var map = new ol.Map({
- * view: new ol.View({
- * center: [0, 0],
- * zoom: 1
- * }),
- * layers: [
- * new ol.layer.Tile({
- * source: new ol.source.OSM()
- * })
- * ],
- * target: 'map'
- * });
- *
- * The above snippet creates a map using a {@link ol.layer.Tile} to display
- * {@link ol.source.OSM} OSM data and render it to a DOM element with the
- * id `map`.
- *
- * The constructor places a viewport container (with CSS class name
- * `ol-viewport`) in the target element (see `getViewport()`), and then two
- * further elements within the viewport: one with CSS class name
- * `ol-overlaycontainer-stopevent` for controls and some overlays, and one with
- * CSS class name `ol-overlaycontainer` for other overlays (see the `stopEvent`
- * option of {@link ol.Overlay} for the difference). The map itself is placed in
- * a further element within the viewport.
- *
- * Layers are stored as a `ol.Collection` in layerGroups. A top-level group is
- * provided by the library. This is what is accessed by `getLayerGroup` and
- * `setLayerGroup`. Layers entered in the options are added to this group, and
- * `addLayer` and `removeLayer` change the layer collection in the group.
- * `getLayers` is a convenience function for `getLayerGroup().getLayers()`.
- * Note that `ol.layer.Group` is a subclass of `ol.layer.Base`, so layers
- * entered in the options or added with `addLayer` can be groups, which can
- * contain further groups, and so on.
