546	If SDL_OpenAudio() is passed zero for the desired format
547	fields, the following environment variables will be used
548	to fill them in:
549<pre><code>
550		SDL_AUDIO_FREQUENCY
551		SDL_AUDIO_FORMAT
552		SDL_AUDIO_CHANNELS
553		SDL_AUDIO_SAMPLES

555	If an environment variable is not specified, it will be set
556	to a reasonable default value.

562	which is set to the desktop resolution during video intialization,
563	and then set to the current resolution when a video mode is set.
564<LI>
565	SDL_GL_LoadLibrary() will load the system default OpenGL library
566	if it is passed NULL as a parameter.
567<LI>
568	Added SDL_GL_SWAP_CONTROL to wait for vsync in OpenGL applications.
569<LI>

607	The XiG XME extension code is now included in the X11 video driver by default.
608<P>
609	XRandR support for video mode switching has been added to the X11 driver, but is disabled because of undesired interactions with window managers.  You can enable this by setting the environment variable SDL_VIDEO_X11_XRANDR to 1.
610<P>
611	Xinerama multi-head displays are properly handled now, and the SDL_VIDEO_FULLSCREEN_HEAD environment variable can be used to select the screen used for fullscreen video modes.  Note that changing the video modes only works on screen 0.
612<P>
613	XVidMode video modes are now sorted so they maintain the refresh rates specified in the X11 configuration file.
614<P>
615	SDL windows are no longer transparent in X11 compositing systems like XGL.
616<P>
617	The mouse is properly released by the X11 video driver if the fullscreen window loses focus.
618<P>
619	The X11 input driver now uses XIM to handle international input.
620<P>
621	The screensaver and DPMS monitor blanking are disabled while SDL games are running under the X11 and DGA video drivers.  This behavior will be formalized and selectable in SDL 1.3.
622<P>
623	Fixed a bug preventing stereo OpenGL contexts from being selected on the X11 driver.
624<P>
625	The DGA video driver now waits for pending blits involving surfaces before they are freed.  This prevents display oddities when using SDL_DisplayFormat() to convert many images.
626<P>
627	The framebuffer console video driver now has a parser for /etc/fb.modes for improved video mode handling.
628<P>
629	The framebuffer console video driver now allows asynchronous VT switching, and restores the full contents of the screen when switched back.
630<P>
631	The framebuffer console now uses CTRL-ALT-FN to switch virtual terminals, to avoid collisions with application key bindings.
632<P>
633	The framebuffer console input driver correctly sets IMPS/2 mode for wheel mice.  It also properly detects when gpm is in IMPS/2 protocol mode, or passing raw protocol from an IMPS/2 mouse.
634<P>
635	The SVGAlib video driver now has support for banked (non-linear) video modes.
636<P>
637	A video driver for OpenBSD on the Sharp Zaurus has been contributed by Staffan Ulfberg.  See the file README.wscons in the SDL source distribution for details.
638<P>
639	Many patches have been incorporated from *BSD ports.

644<BLOCKQUOTE>
645<P>
646	The "windib" video driver is the default now, to prevent problems with certain laptops, 64-bit Windows, and Windows Vista.  The DirectX driver is still available, and can be selected by setting the environment variable SDL_VIDEODRIVER to "directx".
647<P>
648	SDL has been ported to 64-bit Windows.
649<P>
650	Dmitry Yakimov contributed a GAPI video driver for Windows CE.
651<P>
652	The default fullscreen refresh rate has been increased to match the desktop refresh rate, when using equivalent resolutions.  A full API for querying and selecting refresh rates is planned for SDL 1.3.
653<P>
654	Dialog boxes are now shown when SDL is in windowed OpenGL mode.
655<P>
656	The SDL window is recreated when necessary to maintain OpenGL context attributes, when switching between windowed and fullscreen modes.
657<P>
658	An SDL_VIDEORESIZE event is properly sent when the SDL window is maximized and restored.
659<P>
660	Window positions are retained when switching between fullscreen and windowed modes.
661<P>
662	ToUnicode() is used, when available, for improved handling of international keyboard input.
663<P>
664	The PrtScrn is now treated normally with both key down and key up events.
665<P>
666	Pressing ALT-F4 now delivers an SDL_QUIT event to SDL applications.
667<P>
668	Joystick names are now correct for joysticks which have been unplugged and then plugged back in since booting.
669<P>
670	An MCI error when playing the last track on a CD-ROM has been fixed.
671<P>
672	OpenWatcom projects for building SDL have been provided by Marc Peter.

678<P>
679	SDL now supports building Universal binaries, both through Xcode projects and when using configure/make.  See README.MacOSX in the SDL source archive for details.
680<P>
681	The X11 video driver with GLX support can be built on Mac OS X, if the X11 development SDK is installed.
682<P>
683	Transitions between fullscreen resolutions and windowed mode now use a much faster asynchronous fade to hide desktop flicker.
684<P>
685	Icons set with SDL_WM_SetIcon() now have the proper colors on Intel Macs.
