拓展cocos2d-x3.0底层支持etc图片格式，把游戏中的模型使用etc格式的图片替换。
原先可以运行在联想（lenovo S880，显卡类型是PowerVP SG
X 531）的机器上，但是换成etc图片之后进入游戏加载模型的时候就闪退了。
目前大部分其他机型上都没不存在这个问题，只有部分机器会闪退。初步判断有可能是显卡的问题，这个机器的显卡类型是PowerVR SGX 531。不知道各位大大有遇到相同或类似的问题没？

总结出可能导致游戏闪退的原因：
目前大部分其他机型上都没不存在这个问题，只有部分机器会闪退。初步判断有可能是显卡的问题，这个机器的显卡类型是PowerVR SGX 531。不知道各位大大有遇到相同或类似的问题没？
