- * @class CRS
- * @aka L.CRS
- * Abstract class that defines coordinate reference systems for projecting
- * geographical points into pixel (screen) coordinates and back (and to
- * coordinates in other units for [WMS](https://en.wikipedia.org/wiki/Web_Map_Service) services). See

+ * @class Transformation
+ * @aka L.Transformation
  *
  *
- * Leaflet defines the most usual CRSs by default. If you want to use a
- * CRS not defined by default, take a look at the
- * [Proj4Leaflet](https://github.com/kartena/Proj4Leaflet) plugin.
+ * Represents an affine transformation: a set of coefficients `a`, `b`, `c`, `d`
+ * for transforming a point of a form `(x, y)` into `(a*x + b, c*y + d)` and doing
+ * the reverse. Used by Leaflet in its projections code.
+ *
+ * @example
+ *
+ * ```js
+ * var transformation = L.transformation(2, 5, -1, 10),
+ *     p = L.point(1, 2),
+ *     p2 = transformation.transform(p), //  L.point(7, 8)

- * @class Popup
- * @inherits DivOverlay
- * @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.
+/* @section Extension methods
+ * @uninheritable
  *
  *
- * @example
+ * Every layer should extend from `L.Layer` and (re-)implement the following methods.
  *
  *
- * If you want to just bind a popup to marker click and then open it, it's really easy:
+ * @method onAdd(map: Map): this
+ * Should contain code that creates DOM elements for the layer, adds them to `map panes` where they should belong and puts listeners on relevant map events. Called on [`map.addLayer(layer)`](#map-addlayer).
  *
  *
- * ```js
- * 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:
+ * @method onRemove(map: Map): this
+ * Should contain all clean up code that removes the layer's elements from the DOM and removes listeners previously added in [`onAdd`](#layer-onadd). Called on [`map.removeLayer(layer)`](#map-removelayer).
  *
  *
- * ```js
- * var popup = L.popup()
- *     .setLatLng(latlng)
- *     .setContent('<p>Hello world!<br />This is a nice popup.</p>')
- *     .openOn(map);
- * ```
+ * @method getEvents(): Object
+ * This optional method should return an object like `{ viewreset: this._reset }` for [`addEventListener`](#evented-addeventlistener). The event handlers in this object will be automatically added and removed from the map with your layer.
+ *
+ * @method getAttribution(): String
+ * This optional method should return a string containing HTML to be shown on the `Attribution control` whenever the layer is visible.
+ *
+ * @method beforeAdd(map: Map): this
+ * Optional method. Called on [`map.addLayer(layer)`](#map-addlayer), before the layer is added to the map, before events are initialized, without waiting until the map is in a usable state. Use for early initialization only.

+ * (recommended for usability), or use [Map.addLayer](#map-addlayer) to open as many as you want.

+ * ```
+ * Path overlays like polylines also have a `bindPopup` method.

+ *
+ * ```js
+ * var popup = L.popup()

- *
- * @example
- *
- * ```js
- * var baseLayers = {

- *     "OpenStreetMap": osm
- * };
- *
- * var overlays = {
- *     "Marker": marker,
- *     "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:
- *
- * ```js
- * {"<img src='my-layer-icon' /> <span class='my-layer-item'>My Layer</span>": myLayer}
- * ```
