    //          paths to a single mechanism.
    //  3. Use the same single mechanism to support "private" and "user" data.
    //  4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
    //  5. Avoid exposing implementation details on user objects (eg. expando properties)
    //  6. Provide a clear path for implementation upgrade to WeakMap in 2014

       * @class Polygon
       * @aka L.Polygon
       * @inherits Polyline
       *
       * A class for drawing polygon overlays on a map. Extends `Polyline`.
       *
       * Note that points you pass when creating a polygon shouldn't have an additional last point equal to the first one — it's better to filter out such points.
       *
       *
       * @example
       *
       * ```js
       * // create a red polygon from an array of LatLng points
       * var latlngs = [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]];
       *
       * var polygon = L.polygon(latlngs, {color: 'red'}).addTo(map);
       *
       * // zoom the map to the polygon
       * map.fitBounds(polygon.getBounds());
       * ```
       *
       * You can also pass an array of arrays of latlngs, with the first array representing the outer shape and the other arrays representing holes in the outer shape:
       *
       * ```js
       * var latlngs = [
       *   [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring
       *   [[37.29, -108.58],[40.71, -108.58],[40.71, -102.50],[37.29, -102.50]] // hole
       * ];
       * ```
       *
       * Additionally, you can pass a multi-dimensional array to represent a MultiPolygon shape.
       *
       * ```js
       * var latlngs = [
       *   [ // first polygon
       *     [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring
       *     [[37.29, -108.58],[40.71, -108.58],[40.71, -102.50],[37.29, -102.50]] // hole
       *   ],
       *   [ // second polygon
       *     [[41, -111.03],[45, -111.04],[45, -104.05],[41, -104.05]]

       * @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
       *         var size = this.getTileSize();
       *         tile.width = size.x;
       *         tile.height = size.y;
       *
       *         // draw something asynchronously and pass the tile to the done() callback
       *         setTimeout(function() {
       *             done(error, tile);
       *         }, 1000);
       *
       *         return tile;
       *     }
       * });
       * ```

       * Allows vector layers to be displayed with [SVG](https://developer.mozilla.org/docs/Web/SVG).
       * Inherits `Renderer`.
       *
       * Due to [technical limitations](http://caniuse.com/#search=svg), SVG is not
       * available in all web browsers, notably Android 2.x and 3.x.
       *
       * Although SVG is not available on IE7 and IE8, these browsers support
       * [VML](https://en.wikipedia.org/wiki/Vector_Markup_Language)
       * (a now deprecated technology), and the SVG renderer will fall back to VML in
       * this case.
       *
       * @example
       *
       * Use SVG by default for all paths in the map:
       *
       * ```js
       * var map = L.map('map', {
       *        renderer: L.svg()
       * });
       * ```
       *
       * Use a SVG renderer with extra padding for specific vector geometries:
       *
       * ```js
       * var map = L.map('map');
       * var myRenderer = L.svg({ padding: 0.5 });
       * var line = L.polyline( coordinates, { renderer: myRenderer } );
       * var circle = L.circle( center, { renderer: myRenderer } );
       * ```
