q11evc.cpp

涉及的代码是针对WINCE3.0（PPC2002）平台

/*==============================================================================
文件: Q11Evc.cpp
说明：WINCE下小游戏习作，仅博一笑而已，此CPP适应于通用WIN32/WINCE的主窗口建立。 
时间：2003-12-06
编写：oshj || [e-mail]
环境：EVC3.0 or Win2000 Pro/SP4/1024*768分辨率
特别说明：涉及的代码是针对WINCE3.0（PPC2002）平台，同时兼顾了WIN32平台； 旨在
		  讨论编写同时适应2种平台的通用代码；就我现有掌握的资料来看，WINCE平台
		  并不支持DirectX，而WINCE的GAPI又不适合WIN32平台，且无法在模拟器下进行
		  调试（我对GAPI也是一无所知^_^），所以采用了最原始的BitBlt贴图和离屏
		  方式，贴图效果比较粗糙。对声音的处理也比较幼稚，希望不会误导初学者。
		  游戏算法和图片部分参考了王正盛的A10攻击机和Kylinx的kplan代码，在此对
		  两位作者公布源代码的无私行为表示感谢！
