编辑器
目前我的cocos2d-x编辑器的动画部分接口采用的是spriter动画编辑器提供的接口，spriter动画编辑器虽然简陋，但一般的需求基本上能够满足。可以在http://www.brashmonkey.com/spriter.htm下载，另外cocos2d-x的接口可以在论坛http://www.brashmonkey.com/foru
目前我的cocos2d-x编辑器的动画部分接口采用的是spriter动画编辑器提供的接口，spriter动画编辑器虽然简陋，但一般的需求基本上能够满足。可以在http://www.brashmonkey.com/spriter.htm下载，另外cocos2d-x的接口可以在论坛http://www.brashmonkey.com/forum/viewtopic.php?f=3&t=870下载。
接口导入进来之后，一切都很正常，然而在采用该接口进行开发时，发现有几个比较严重的问题。
问题1：资源采用多文件夹形式存储，渲染效率低
问题2：一个png只能有一个ccsprite，在编辑器是正常的，然而采用论坛那个接口导入到cocos2d-x就有问题。
问题3：精灵不能flip
问题4：不支持scale变换
陆续修改了上述4个问题
资源采用Sprite Frame实现
png的bug线性实现，时间复杂度O（1）
flip的实现参考cocos2d-x源码中CCTransitionFlipX的实现——摄像头换位
scale参考angle的变换就OK了
代码如下：
（代码中掺杂了编辑器部分的代码，精力有限，本代码仅供参考）
