* 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)
