 * The Emitter no longer checks if minParticleScale = maxParticleScale for the scale check, allowing for fixed scale particles again.
 * The PIXI.AbstractFilter is now included in the Phaser Pixi build by default, allowing for easier use of external Pixi Filters.
 * All Game Objects have a new property: destroyPhase (boolean) which is true if the object is in the process of being destroyed, otherwise false.
