// 1. Enforce API surface and semantic compatibility with 1.9.x branch

// 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

*
* @example
*
* ```js
* map.on('click', function(e) {
* alert(e.latlng);
* } );

*
* Leaflet deals with event listeners by reference, so if you want to add a listener and then remove it, define it as a function:

*
* map.on('click', onClick);
* map.off('click', onClick);

*
* // 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

*
* Additionally, you can pass a multi-dimensional array to represent a MultiPolygon shape.
*
* ```js
* var latlngs = [
* [ // first polygon

* @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;
* }
* });
* ```
