* A Matter Mouse Spring will disable debug draw of its constraint by default (you can override it by passing in your own config)
* Removed Camera.clearBeforeRender property as it was never used internally. This setting can be enabled on a Game-wide basis.
* Camera now extends the Event Emitter, allowing it to emit events.
