Subject: SDL x11 video mode selection bug
Hi, I've found an oddity with video mode selection. I recently added a bunch of
oddball video modes to my XF86Config, to support weird resolutions xine &
mplayer need if I don't want to beat my cpu up with video scaling.
Since adding them, SDL started picking the biggest video mode it could find
that matched the height constraint. Getting a narrow vertical strip of
QuakeForge (I code for the project, so needless to say it's my favorite test)
in the middle of an 800x480 screen, instead of the 640x480 I asked for
annoys me tremendously.
So here's a patch that tries a bit harder to get an exact match. I didn't
touch the XiG section, since I can't test that, but I'd bet a similar patch
would prevent similar problems there.
