javascript – 如何在没有Stage的情况下使用pixi.js？

var stage,renderer,graphics;

    (function () {
      // init PIXI
      // create an new instance of a pixi stage
      stage = new PIXI.Stage(0x66FF99);

      // create a renderer instance.
      renderer = PIXI.autoDetectRenderer(400,300);

      $('#pixi-area').append(renderer.view);

      graphics = new PIXI.Graphics();
      graphics.beginFill(0xFFFFFF);
      graphics.linestyle(1,0xFF0000);
      graphics.drawRect(20,20,150,150);
      stage.addChild(graphics);
      renderer.render(stagE);
    }());

但是,在控制台中我得到了声明

You do not need to use a PIXI Stage any more,you can simply render any container.

如果不使用PIXI.Stage(),我该如何做同样的事情？
