SDL_CD - CDROM Drive Information

       An  SDL_CD  structure  is  returned  by  SDL_CDOpen.  It  represents  an  opened  CDROM device and stores
       information on the layout of the tracks on the disc.

       A frame is the base data unit of a CD. CD_FPS frames is equal to 1 second  of  music.  SDL  provides  two
       macros for converting between time and frames: FRAMES_TO_MSF(f,M,S,F) and MSF_TO_FRAMES.

       int min, sec, frame;
       int frame_offset;

       FRAMES_TO_MSF(cdrom->cur_frame, &min, &sec, &frame);
       printf("Current Position: %d minutes, %d seconds, %d frames
       ", min, sec, frame);

       frame_offset=MSF_TO_FRAMES(min, sec, frame);
