 *
 *  Changes:
 *    Dominik Schnitzer <dominik@schnitzer.at> - November 08, 2000.
 *    - Added resizing support, fullscreen: changed 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
 *    Felix Buenemann <Atmosfear@users.sourceforge.net> - March 11, 2001
 *    - Added aspect-ratio awareness for fullscreen
 *    Felix Buenemann <Atmosfear@users.sourceforge.net> - March 11, 2001
 *    - Fixed aspect-ratio awareness, did only vertical scaling (black bars above
 *       and below), now also does horizontal scaling (black bars left and right),
 *       so you get the biggest possible picture with correct aspect-ratio.
 *    Felix Buenemann <Atmosfear@users.sourceforge.net> - March 12, 2001
 *    - Minor bugfix to aspect-ratio for non-4:3-resolutions (like 1280x1024)
 *    - Bugfix to check_events() to reveal mouse cursor after 'q'-quit in
 *       fullscreen-mode
 *    Felix Buenemann <Atmosfear@users.sourceforge.net> - April 10, 2001
 *    - Changed keypress-detection from keydown to keyup, seems to fix keyrepeat
 *       bug (key had to be pressed twice to be detected)
 *    - Changed key-handling: 'f' cycles fullscreen/windowed, ESC/RETURN/'q' quits
 *    - Bugfix which avoids exit, because return is passed to sdl-output on startup,
 *       which caused the player to exit (keyboard-buffer problem? better solution
 *       recommed)
 *    Felix Buenemann <Atmosfear@users.sourceforge.net> - April 11, 2001
 *    - OSD and subtitle support added
 *    - some minor code-changes
 *    - added code to comply with new fullscreen meaning
 *    - changed fullscreen-mode-cycling from '+' to 'c' (interferred with audiosync
 *       adjustment)
 *    Felix Buenemann <Atmosfear@users.sourceforge.net> - April 13, 2001
 *    - added keymapping to toggle OSD ('o' key) 
 *    - added some defines to modify some sdl-out internas (see comments)
 *
 *    Felix Buenemann: further changes will be visible through cvs log, don't want
 *     to update this all the time (CVS info on http://mplayer.sourceforge.net)
