/**
* The Loader handles loading all external content such as Images, Sounds, Texture Atlases and data files.
2015-03-23 23:46:30 +00:00
*
* The loader uses a combination of tag loading (eg. Image elements) and XHR and provides progress and completion callbacks.
*
* Parallel loading (see {@link #enableParallel}) is supported and enabled by default.
* Load-before behavior of parallel resources is controlled by synchronization points as discussed in {@link #withSyncPoint}.
*
* Texture Atlases can be created with tools such as [Texture Packer](https://www.codeandweb.com/texturepacker/phaser) and
* [Shoebox](http://renderhjs.net/shoebox/)
