  18  *  -- old disclaimer --
  19  *
  20  *  A mpeg2dec display driver that does output through the
  21  *  Simple DirectMedia Layer (SDL) library. This effectively gives us all
  22  *  sorts of output options: X11, SVGAlib, fbcon, AAlib, GGI. Win32, MacOS
  23  *  and BeOS support, too. Yay. SDL info, source, and binaries can be found
  24  *  at http://slouken.devolution.com/SDL/
