/** @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
