/**
* Phaser - World
*
* A game has only one world. The world is an abstract place in which all game objects live. It is not bound
* by stage limits and can be any size or dimension. You look into the world via cameras and all game objects
* live within the world at world-based coordinates. By default a world is created the same size as your Stage.
