- * L.Transformation is an utility class to perform simple point transformations through a 2d-matrix.
+ * @class LatLngBounds
+ * @aka L.LatLngBounds
+ *
+ * Represents a rectangular geographical area on a map.
+ *
+ * @example
+ *
+ * ```js
+ * var corner1 = L.latLng(40.712, -74.227),
+ * corner2 = L.latLng(40.774, -74.125),
+ * bounds = L.latLngBounds(corner1, corner2);
+ * ```
+ *
+ * All Leaflet methods that accept LatLngBounds objects also accept them in a simple Array form (unless noted otherwise), so the bounds example above can be passed like this:
+ *
+ * ```js
+ * map.fitBounds([
+ * 	[40.712, -74.227],
+ * 	[40.774, -74.125]
+ * ]);
+ * ```
+ *
+ * Caution: if the area crosses the antimeridian (often confused with the International Date Line), you must specify corners _outside_ the [-180, 180] degrees longitude range.
+ *
+ * Note that `LatLngBounds` does not inherit from Leafet's `Class` object,
+ * which means new classes can't inherit from it, and new methods
+ * can't be added to it with the `include` function.

+ *
+ *
+ * @example

+ * // 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

+ *
+ * ```js
+ * var latlngs = [
+ *   [ // first polygon
+ *     [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring

- * L.Draggable allows you to add dragging capabilities to any element. Supports mobile devices too.
+ * @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
+ *         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;

+ * (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 } );
