Date: Mon, 17 Jan 2005 20:54:50 +0200 From: Ville [snip] Subject: [PATCH] SDL/DirectFB: remove Matrox CRTC2 flicker filter Hi, This patch removes the flicker filter option from the DirectFB backend's Matrox CRTC2 code in SDL. I will be removing the option from DirectFB (because it doesn't actually work) and that would cause the SDL code to fail without this fix. I was going to send this to some SDL list directly but libsdl.org is down so I'm not sure what if any lists there are. Thomas Jarosch (the guy who wrote the code) said you would accept SDL patches. Let me know if I should send this somewhere else. -- Ville Syrj�l� syrjala _at sci.fi http://www.sci.fi/~syrjala/
