* "This world is but a canvas to our imagination." - Henry David Thoreau

|

* 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. You look into the world via cameras. All game objects live within
|
||||
* the world at world-based coordinates. By default a world is created the same size as your Stage.
