The SetVisibleSurfacefunction causes an existing GPEsurface to be flipped to the display. If the bWaitForVBlank parameter is TRUE, the function waits until the vertical blank has begun, then it flips the given surface to the screen.
You should override this function in your driver to enable surface flipping for your hardware. dwData can be used if you need to pass more information to perform the flip.
virtual void SetVisibleSurface ( GPESurf * pSurf , BOOL bWaitForVBlank = FALSE); virtual void SetVisibleSurface ( GPESurf * pSurf , DWORD dwData , BOOL bWaitForVBlank = FALSE );
