mfc简单换肤

      mfc程序的界面一向是大家所诟病的，我之前在写微笔记的时候一直痛心界面的丑陋，所以我下定决定自己写一个换肤的库，虽然有不少bug，但是毕竟是自己的成果，还是蛮开心的。

       这个换肤是挂钩WH_CBT钩子，这个钩子会在窗口的创建前和销毁前响应，正好适合我们在这里子类化来修改新窗口的消息处理函数，我们把修改的窗口保存到一个map里，然后当窗口销毁时还原原来的消息处理函数，在绘制的过程中，CStatic我用的是wm_paint消息，而其他的控件我用的是owner draw。在这里我发现一点，就是在一个窗体owner draw之前会判断当前有没有无效区，也就是调用beginpaint函数，要是调用了，就不会owner draw，因为子窗体在wm_paint里已经自我绘制了，就不需要交给父窗体来帮他绘制。

        换肤很简单，在mfc的InitInstance中，主窗体doModal前调用InitMySkin()即可，释放在ExitInstance中调用UninitMySkin()即可。
