Phaser.TilemapParser.INSERT_NULL is a new boolean that controls what happens when the parser encounters an empty tile: When scanning the Tiled map data the TilemapParser can either insert a null value (true) or a Phaser.Tile instance with an index of -1 (false, the default). Depending on your game type depends how this should be configured. If you've a large sparsely populated map and the tile data doesn't need to change then setting this value to true will help with memory consumption. However if your map is small, or you need to update the tiles (perhaps the map dynamically changes during the game) then leave the default value set (thanks #1982)

It can draw Text, BitmapText, Sprites, Images, Emitters and Graphics objects. It's perfectly valid to pass in `game.world` as the parent object, and it will iterate through the entire display list.
