/** @brief FastTMXTiledMap knows how to parse and render a TMX map.

 * It adds support for the TMX tiled map format used by http://www.mapeditor.org.
 * It supports isometric, hexagonal and orthogonal tiles.
 * It also supports object groups, objects, and properties.

 * Features:
 * - Each tile will be treated as an Sprite.
 * - The sprites are created on demand. They will be created only when you call "layer->tileAt(position)".
 * - Each tile can be rotated / moved / scaled / tinted / "opaqued", since each tile is a Sprite.
 * - Tiles can be added/removed in runtime.
 * - The z-order of the tiles can be modified in runtime.
 * - Each tile has an anchorPoint of (0,0).
 * - The anchorPoint of the TMXTileMap is (0,0).
 * - The TMX layers will be added as a child.
 * - The TMX layers will be aliased by default.
 * - The tileset image will be loaded using the TextureCache.
 * - Each tile will have a unique tag.
 * - Each tile will have a unique z value. top-left: z=1, bottom-right: z=max z.
 * - Each object group will be treated as an MutableArray.
 * - Object class which will contain all the properties in a dictionary.
 * - Properties can be assigned to the Map, Layer, Object Group, and Object.

 * Limitations:
 * - It only supports one tileset per layer.
 * - Embedded images are not supported.
 * - It only supports the XML format (the JSON format is not supported).

 * Technical description:
 * Each layer is created using an FastTMXLayer (subclass of SpriteBatchNode). If you have 5 layers, then 5 FastTMXLayer will be created,
 * unless the layer visibility is off. In that case, the layer won't be created at all.
 * You can obtain the layers (FastTMXLayer objects) at runtime by:
 * - map->getChildByTag(tag_number);  // 0=1st layer, 1=2nd layer, 2=3rd layer, etc...
 * - map->getLayer(name_of_the_layer);

 * Each object group is created using a TMXObjectGroup which is a subclass of MutableArray.
 * You can obtain the object groups at runtime by:
 * - map->getObjectGroup(name_of_the_object_group);

 * Each object is a TMXObject.

 * Each property is stored as a key-value pair in an MutableDictionary.
 * You can obtain the properties at runtime by:

 * map->getProperty(name_of_the_property);
 * layer->getProperty(name_of_the_property);
 * objectGroup->getProperty(name_of_the_property);
 * object->getProperty(name_of_the_property);

 * @since v3.2
 * @js NA
