/*!
 * @file ScrollMagic jQuery plugin.
 *
 * requires: jQuery >=1.11
 */
/**
 * This plugin is meant to be used in conjunction with jQuery.  
 * It enables ScrollMagic to make use of jQuery's advanced selector engine (sizzle) for all elements supplied to ScrollMagic objects, like scroll containers or trigger elements.  
 * ScrollMagic also accepts jQuery elements for all methods that expect references to DOM elements. Please note, that in most cases the first element of the matched set will be used.
 * 
 * Additionally it provides the ScrollMagic object within the jQuery namespace, so it can be accessed using `$.ScrollMagic`.
 *
 * In contrast to most other plugins it does not offer new API additions for ScrollMagic.
 *
 * To have access to this extension, please include `plugins/jquery.ScrollMagic.js`.
 * @example
 * // create a new scene making use of jQuery's advanced selector engine
 * var scene = new $.ScrollMagic.Scene({
 *   triggerElement: "#parent div.trigger[attr='thisone']:not(.notthisone)"
 * });
 * @requires {@link http://jquery.com/|jQuery >=1.11}
 * @mixin framework.jQuery
