+ * video_out_sdl.c
+ *
+ * Copyright (C) Ryan C. Gordon <icculus@lokigames.com> - April 22, 2000.
+ *
+ * A mpeg2dec display driver that does output through the
+ * Simple DirectMedia Layer (SDL) library. This effectively gives us all
+ * sorts of output options: X11, SVGAlib, fbcon, AAlib, GGI. Win32, MacOS
+ * and BeOS support, too. Yay. SDL info, source, and binaries can be found
+ * at http://slouken.devolution.com/SDL/

+ * Changes:
+ * Dominik Schnitzer <dominik@schnitzer.at> - November 08, 2000.
+ * - Added resizing support, fullscreen: chnaged the sdlmodes selection
+ * routine.
+ * - SDL bugfixes: removed the atexit(SLD_Quit), SDL_Quit now resides in
+ * the plugin_exit routine.
+ * - Commented the source :)
+ * - Shortcuts: for switching between Fullscreen/Windowed mode and for
+ * cycling between the different Fullscreen modes.
+ * - Small bugfixes: proper width/height of movie
+ * Dominik Schnitzer <dominik@schnitzer.at> - November 11, 2000.
+ * - Cleanup code, more comments
+ * - Better error handling
+ * Bruno Barreyra <barreyra@ufl.edu> - December 10, 2000.
+ * - Eliminated memcpy's for entire frames
