关于绘制刷新闪烁问题

该图形库在呈现动画效果时往往会发生画面的闪烁，原因是窗口的WndProc函数，即指定的static LONG FAR PASCAL GraphicsEventProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)；中，将msg的一个可能值WM_ERASEBKGND归入了default case，进入了DefWindowProc，然而该行为会导致窗口被全部刷白一次，故即使使用了双缓冲仍然会闪烁。只要加一个针对WM_ERASEBKGND的case然后直接返回0就可以避免闪烁哩！（详细内容可见这位大哥的仓库文档https://github.com/Kouek/Mini3DWithLibGraphics/blob/master/doc/ModifyLibGraphics-NoBlink.md）
