Fixed bug #80
Date: 21 Apr 2003 17:20:20 +0100
From: Alan Swanson <swanson@uklinux.net>
Subject: [SDL] New XFree 4.3 Video Mode Patch
If you look at the unsorted list of modes returned by X, here's mine;
1280 x 1024 @ 85.0 >
1024 x 768 @ 100.3 > USER
800 x 600 @ 125.5 > SET
640 x 480 @ 124.9 >
1280 x 1024 @ 75.0 ]
1280 x 1024 @ 60.0 ]
1280 x 960 @ 85.0 ] X11
1280 x 960 @ 60.0 ] AUTO
1152 x 864 @ 75.0 ]=20
1152 x 768 @ 54.8 ]
960 x 720 @ 120.0 ]
...
640 x 400 @ 85.1 ] 256k
576 x 432 @ 150.0 ] 249k PIXEL
640 x 350 @ 85.1 ] 224k COUNT
576 x 384 @ 109.6 ] 221k
...
The user set modes come first followed by X set modes which are ordered
by decreasing number of pixels and refresh.
The reason why every other library or program not using SDL working is
due to SDL scanning the modes in reverse getting X11 provided modes
modes with the lowest refresh.

Ugh, more 64-bit cleanup

Added documentation on how to build a completely useless SDL library. :)

Removed atexit() from most of the test programs; atexit(SDL_Quit) isn't safe
