 * @property {boolean} isLayer - Used to checkout whether this layer is a Layer.

 * optimisation.
 * @property {boolean} ready - This property is false when the layer isn't added.
 * It's true when the layer is added and all initializations are done.
 * @property {Source} source - This source determines the datas to be displayed with the layer.
 * The layer determines how this data are displayed.
 * By example:
 * * For ColorLayer/ElevationLayer, the source datas are rasterised (if it's necessary).
 * * For GeometryLayer, the source datas are converted to meshes (not possible for the raster data sources).
 * @property {Promise} whenReady - this promise is resolved when the layer is added and all initializations are done.
 * This promise is resolved with this layer.
 * This promise is returned by [View#addLayer]{@link View}.
 * @property {boolean} [addLabelLayer=false] - Used to tell if this layer has
 * labels to display from its data. For example, it needs to be set to `true`
 * for a layer with vector tiles. If it's `true` a new `LabelLayer` is added and attached to this `Layer`.
 * @property {object} [zoom] - This property is used only the layer is attached to [TiledGeometryLayer]{@link TiledGeometryLayer}.
 * By example,
 * The layer checks the tile zoom level to determine if the layer is visible in this tile.
 *
 * ![tiled geometry](/docs/static/images/wfszoommaxmin.jpeg)

 * _In this example [WFS to 3D objects](http://www.itowns-project.org/itowns/examples/index.html#source_stream_wfs_3d), the building layer zoom min is 14._
 * _In the lower part of the picture, the zoom tiles 14 have buildings, while in the upper part of the picture, the level 13 tiles have no buildings._
 *
 * @property {number} [zoom.max=Infinity] - this is the maximum zoom beyond which it'll be hidden.
 * @property {number} [zoom.min=0] - this is the minimum zoom from which it'll be visible.
