			/**
			 * @constructor
			 * Defines a GreenSock class, optionally with an array of dependencies that must be instantiated first and passed into the definition.
			 * This allows users to load GreenSock JS files in any order even if they have interdependencies (like CSSPlugin extends TweenPlugin which is
			 * inside TweenLite.js, but if CSSPlugin is loaded first, it should wait to run its code until TweenLite.js loads and instantiates TweenPlugin
			 * and then pass TweenPlugin to CSSPlugin's definition). This is all done automatically and internally.
			 *
			 * Every definition will be added to a "com.greensock" global object (typically window, but if a window.GreenSockGlobals object is found,
			 * it will go there as of v1.7). For example, TweenLite will be found at window.com.greensock.TweenLite and since it's a global class that should be available anywhere,
			 * it is ALSO referenced at window.TweenLite. However some classes aren't considered global, like the base com.greensock.core.Animation class, so
			 * those will only be at the package like window.com.greensock.core.Animation. Again, if you define a GreenSockGlobals object on the window, everything
			 * gets tucked neatly inside there instead of on the window directly. This allows you to do advanced things like load multiple versions of GreenSock
			 * files and put them into distinct objects (imagine a banner ad uses a newer version but the main site uses an older one). In that case, you could
			 * sandbox the banner one like:
			 *
			 * <script>
			 *     var gs = window.GreenSockGlobals = {}; //the newer version we're about to load could now be referenced in a "gs" object, like gs.TweenLite.to(...). Use whatever alias you want as long as it's unique, "gs" or "banner" or whatever.
			 * </script>
			 * <script src="js/greensock/v1.7/TweenMax.js"></script>
			 * <script>
			 *     window.GreenSockGlobals = window._gsQueue = window._gsDefine = null; //reset it back to null (along with the special _gsQueue variable) so that the next load of TweenMax affects the window and we can reference things directly like TweenLite.to(...)
			 * </script>
			 * <script src="js/greensock/v1.6/TweenMax.js"></script>
			 * <script>
			 *     gs.TweenLite.to(...); //would use v1.7
			 *     TweenLite.to(...); //would use v1.6
			 * </script>
			 *
			 * @param {!string} ns The namespace of the class definition, leaving off "com.greensock." as that's assumed. For example, "TweenLite" or "plugins.CSSPlugin" or "easing.Back".
			 * @param {!Array.<string>} dependencies An array of dependencies (described as their namespaces minus "com.greensock." prefix). For example ["TweenLite","plugins.TweenPlugin","core.Animation"]
			 * @param {!function():Object} func The function that should be called and passed the resolved dependencies which will return the actual class for this definition.
			 * @param {boolean=} global If true, the class will be added to the global scope (typically window unless you define a window.GreenSockGlobals object)

Imagine doing a timeline.seek(0) and there's a callback that sits at 0. Since events are suppressed on that seek() by default, nothing will fire, but when the playhead moves off of that position, the callback should fire. This behavior is what people intuitively expect.
