+	Node for 2D tile-based games. Tilemaps use a [TileSet] which contain a list of tiles (textures, their rect and a collision) and are used to create complex grid-based maps.
 	To optimize drawing and culling (sort of like [GridMap]), you can specify a quadrant size, so chunks of the map will be batched together at drawing time.
