- * @class GridLayer
- * @inherits Layer
- * @aka L.GridLayer
- *
- * Generic class for handling a tiled grid of HTML elements. This is the base class for all tile layers and replaces `TileLayer.Canvas`.
- * GridLayer can be extended to create a tiled grid of HTML elements like `<canvas>`, `<img>` or `<div>`. GridLayer will handle creating and animating these DOM elements for you.
- *
- *
- * @section Synchronous usage
- * @example
- *
- * To create a custom layer, extend GridLayer and implement the `createTile()` method, which will be passed a `Point` object with the `x`, `y`, and `z` (zoom level) coordinates to draw your tile.
- *
- * ```js
- * var CanvasLayer = L.GridLayer.extend({
- *     createTile: function(coords){
- *         // create a <canvas> element for drawing
- *         var tile = L.DomUtil.create('canvas', 'leaflet-tile');
- *
- *         // setup tile width and height according to the options
- *         var size = this.getTileSize();
- *         tile.width = size.x;
- *         tile.height = size.y;
- *
- *         // get a canvas context and draw something on it using coords.x, coords.y and coords.z
- *         var ctx = tile.getContext('2d');
- *
- *         // return the tile so it can be rendered on screen
- *         return tile;
- *     }
- * });
- * ```
- *
- * @section Asynchronous usage
- * @example
- *
- * Tile creation can also be asynchronous, this is useful when using a third-party drawing library. Once the tile is finished drawing it can be passed to the `done()` callback.
- *
- * ```js
- * var CanvasLayer = L.GridLayer.extend({
- *     createTile: function(coords, done){
- *         var error;
- *
- *         // create a <canvas> element for drawing
- *         var tile = L.DomUtil.create('canvas', 'leaflet-tile');
- *
- *         // setup tile width and height according to the options

+ * GridLayer can be extended to create a tiled grid of HTML elements like `<canvas>`, `<img>` or `<div>`. GridLayer will handle creating and animating these DOM elements for you.
+ *
+ *
+ * @section Synchronous usage
+ * @example
+ *
+ * To create a custom layer, extend GridLayer and implement the `createTile()` method, which will be passed a `Point` object with the `x`, `y`, and `z` (zoom level) coordinates to draw your tile.
+ *
+ * ```js
+ * var CanvasLayer = L.GridLayer.extend({
+ *     createTile: function(coords){
+ *         // create a <canvas> element for drawing

  * @inherits DivOverlay
- * @aka L.Tooltip
- * Used to display small texts on top of map layers.
+ * @aka L.Popup
+ * Used to open popups in certain places of the map. Use [Map.openPopup](#map-openpopup) to
+ * open popups while making sure that only one popup is open at one time
+ * (recommended for usability), or use [Map.addLayer](#map-addlayer) to open as many as you want.
  *
  * @example
  *
  *
  * @example
  *
+ * If you want to just bind a popup to marker click and then open it, it's really easy:
+ *
  * ```js
  * ```js
- * marker.bindTooltip("my tooltip text").openTooltip();
+ * marker.bindPopup(popupContent).openPopup();
+ * ```
+ * Path overlays like polylines also have a `bindPopup` method.
+ * Here's a more complicated way to open a popup on a map:
+ *
+ * ```js
+ * var popup = L.popup()
+ *     .setLatLng(latlng)
+ *     .setContent('<p>Hello world!<br />This is a nice popup.</p>')
+ *     .openOn(map);
  * ```
  * ```
- * Note about tooltip offset. Leaflet takes two options in consideration
- * for computing tooltip offseting:
- * - the `offset` Tooltip option: it defaults to [0, 0], and it's specific to one tooltip.
- *   Add a positive x offset to move the tooltip to the right, and a positive y offset to
- *   move it to the bottom. Negatives will move to the left and top.
- * - the `tooltipAnchor` Icon option: this will only be considered for Marker. You
- *   should adapt this value if you use a custom icon.

- * A class for drawing circle overlays on a map. Extends `CircleMarker`.
+ * Base class for vector renderer implementations (`SVG`, `Canvas`). Handles the
+ * DOM container of the renderer, its bounds, and its zoom animation.
  *
  *
- * It's an approximation and starts to diverge from a real circle closer to poles (due to projection distortion).
+ * A `Renderer` works as an implicit layer group for all `Path`s - the renderer
+ * itself can be added or removed to the map. All paths use a renderer, which can
+ * be implicit (the map will decide the type of renderer and use it automatically)
+ * or explicit (using the [`renderer`](#path-renderer) option of the path).
  *
  *
- * @example
+ * Do not use this class directly, use `SVG` and `Canvas` instead.
  *
  *
- * ```js
- * L.circle([50.5, 30.5], {radius: 200}).addTo(map);
- * ```
+ * @event update: Event
+ * Fired when the renderer updates its bounds, center and zoom, for example when
+ * its map has moved

- * @aka L.Canvas
- *
- * Allows vector layers to be displayed with [`<canvas>`](https://developer.mozilla.org/docs/Web/API/Canvas_API).
- * Inherits `Renderer`.
+ * @class Polyline
+ * @aka L.Polyline
+ * @inherits Path
  *
  *
- * Due to [technical limitations](http://caniuse.com/#search=canvas), Canvas is not
- * available in all web browsers, notably IE8, and overlapping geometries might
- * not display properly in some edge cases.
+ * A class for drawing polyline overlays on a map. Extends `Path`.
  *
  * @example
  *
  *
  * @example
  *
- * Use Canvas by default for all paths in the map:
- *
  * ```js
  * ```js
- * var map = L.map('map', {
- *     renderer: L.canvas()
- * });
+ * // create a red polyline from an array of LatLng points
+ * var latlngs = [
+ *     [-122.68, 45.51],
+ *     [-122.43, 37.77],
+ *     [-118.2, 34.04]
+ * ];
+ *
+ * var polyline = L.polyline(latlngs, {color: 'red'}).addTo(map);
+ *
+ * // zoom the map to the polyline
+ * map.fitBounds(polyline.getBounds());
  * ```
  *
  * ```
  *
- * Use a Canvas renderer with extra padding for specific vector geometries:
+ * You can also pass a multi-dimensional array to represent a `MultiPolyline` shape:
  *
  * ```js
  *
  * ```js
- * var map = L.map('map');
- * var myRenderer = L.canvas({ padding: 0.5 });
- * var line = L.polyline( coordinates, { renderer: myRenderer } );
- * var circle = L.circle( center, { renderer: myRenderer } );
+ * // create a red polyline from an array of arrays of LatLng points
+ * var latlngs = [
+ *     [[-122.68, 45.51],

- * };
- *
- * var overlays = {

- *     "Roads": roadsLayer
- * };
- *
- * L.control.layers(baseLayers, overlays).addTo(map);
- * ```
- *
- * The `baseLayers` and `overlays` parameters are object literals with layer names as keys and `Layer` objects as values:
- *
- * ```js
- * {
- *     "<someName1>": layer1,
- *     "<someName2>": layer2
- * }
- * ```
- *
- * The layer names can contain HTML, which allows you to add additional styling to the items:
+ * @class Control
+ * @aka L.Control
+ * @inherits Class
  *
  *
- * ```js
- * {"<img src='my-layer-icon' /> <span class='my-layer-item'>My Layer</span>": myLayer}
