* The Spine loader is used to load in JSON spine data
* To generate the data you need to use http:&#x2F;&#x2F;esotericsoftware.com&#x2F; and export the &quot;JSON&quot; format
* Due to a clash of names You will need to change the extension of the spine file from *.json to *.anim for it to load
* See example 12 (http:&#x2F;&#x2F;www.goodboydigital.com&#x2F;pixijs&#x2F;examples&#x2F;12&#x2F;) to see a working example and check out the source
* You will need to generate a sprite sheet to accompany the spine data
* When loaded this class will dispatch a &quot;loaded&quot; event
* @class Spine
* @constructor
* @extends EventTarget
* @param {String} url the url of the sprite sheet JSON file
* @param {Boolean} crossorigin
*&#x2F;
