[]设置transform.localRotation之后，就不能再使用transform.rotate了

自己先在谷歌浏览器里debug调试下，看每行代码执行后，物体的世界矩阵是否发生变化！

我使用的版本是 1.7.2 beta附件是测试例子，是一个nodejs工程。用node app.js --port=8888启动服务器，浏览器访问localhost:8888
等界面显示之后在console中输入test()
这会创建两张牌，第一张牌在右侧，第二张在左侧。
第一张牌使用了localRotation，可以看到旋转无效了，console中的matrix也可以看到是不变的
第二张牌直接rotate，可以看到旋转了。
 
顺便问一下，要想知道Sprite3D.load加载完成，只能继承并重写onAsynLoaded？
-------------------------------------------------------------------------------------ok, 我检查了worldMatrix，确实在设置了localRotation之后就不再变化了，why？
