* DEPRECATION: Viewer's layer-level-changed event is now World's item-index-change event
* DEPRECATION: Viewer's remove-layer event is now World's remove-item event
* DEPRECATION: Viewer's add-layer-failed event is now add-item-failed
* DEPRECATION: TileSourceCollection has been retired in favor of World
