partly updated for windows xp and windows 2003, the above struct is from yaun book

NOTE : if any of these flags are set in dwCallbackFlags (struct EDD_DIRECTDRAW_GLOBAL), it means that the respective callback member for it has been filled in by a graphic driver

  2. define EDDDGBL_VIDEOPORTCALLBACKS 0x02 // ddVideoPortCallback
