 * //or
 * const loader = new PIXI.loaders.Loader(); // you can also create your own if you want
 *
 * const sprites = {};
 *
 * // Chainable `add` to enqueue a resource
 * loader.add('bunny', 'data/bunny.png')
 *       .add('spaceship', 'assets/spritesheet.json');
 * loader.add('scoreFont', 'assets/score.fnt');
 *
 * // Chainable `pre` to add a middleware that runs for each resource, *before* loading that resource.
 * // This is useful to implement custom caching modules (using filesystem, indexeddb, memory, etc).
 * loader.pre(cachingMiddleware);
 *
 * // Chainable `use` to add a middleware that runs for each resource, *after* loading that resource.
 * // This is useful to implement custom parsing modules (like spritesheet parsers, spine parser, etc).
 * loader.use(parsingMiddleware);
 *
 * // The `load` method loads the queue of resources, and calls the passed in callback called once all
 * // resources have loaded.
 * loader.load((loader, resources) => {
 *     // resources is an object where the key is the name of the resource loaded and the value is the resource object.
 *     // They have a couple default properties:
 *     // - `url`: The URL that the resource was loaded from
 *     // - `error`: The error that happened when trying to load (if any)
 *     // - `data`: The raw data that was loaded
 *     // also may contain other properties based on the middleware that runs.
 *     sprites.bunny = new PIXI.TilingSprite(resources.bunny.texture);
 *     sprites.spaceship = new PIXI.TilingSprite(resources.spaceship.texture);

 * });
 *
 * // throughout the process multiple signals can be dispatched.
 * loader.onProgress.add(() => {}); // called once per loaded/errored file
 * loader.onError.add(() => {}); // called once per errored file
 * loader.onLoad.add(() => {}); // called once per loaded file
