/**
 * @classdesc
 * A Dynamic Tilemap Layer is a Game Object that renders LayerData from a Tilemap when used in combination
 * with one, or more, Tilesets.
 *
 * A Dynamic Tilemap Layer trades some speed for being able to apply powerful effects. Unlike a
 * Static Tilemap Layer, you can apply per-tile effects like tint or alpha, and you can change the
 * tiles in a DynamicTilemapLayer.
 * 
 * Use this over a Static Tilemap Layer when you need those features.
