利用DirectDraw创建双表面。DirectDraw允许用户直接对显示内存操作，支持硬件位块传输、硬件覆盖、表面翻转、纹理映射和镜像。-using DirectDraw create dual surface. DirectDraw allows users to direct memory operation, support hardware bit block transfers, hardware coverage, reversed the surface, texture map

使用DirectDraw画线。表面是一个按线性排列的内存块，它可以用一个char数组来描述。通过调用IDirectDrawSurface::Lock()方法，就可以访问与每个表面相关的内存。-using DirectDraw line drawing. The surface is a linear arrangement on the block of memory, it can use a char array to describe. By calling IDirectDrawSurf
