EVC下實現WinCE軟件換膚之換膚基礎類CBitmapSK

由于在wince下不支持hook，所以對ce下的軟件換膚，會很慧心，不過，曾經看到過一個國外的網站上有pocket下實現hook的代碼，沒讀懂，呵呵，自己太水了,這就涉及到另外一個問題了，還沒有找到實現hook的方法，所有要另外想辦法了，所以不管怎么樣都要重寫控件，參考了一些VC實現的換膚，在此實現了基本類CBitmapSK。其中有個郁悶的地方是evc對CRgn支持的不全面，對任意形狀的窗口實現有些麻煩，所以有個重要的函數不能實現，要想其他的辦法實現，

使用這個類實現了對話筐的換膚，測試還行。

暫時還沒發現ce下的換膚第三方控件，見過最好的也就是那個CCeButton了，還是在EVC3.0下開發的。。。
