BulkLoader类和PV3D

AS3取消了movieclip的loader类，所以加载图片除了用

img = new Loader();
img.load(new URLRequest("assets/materials/c.png"));
//加载完成后的事件响应
img.contentLoaderInfo.addEventListener(Event.COMPLETE, setup);

就没有其他办法了，特别在要载入大量图片的环境下，就很难使用。
前几天发现了BulkLoader，大大简化了载入图片所需的步骤。而且可以对应各种格式，比如xml,video,声音,图片等文件。下面这个例子就是和pv3d结合使用的例子。
