Date: Fri, 24 May 2002 10:32:00 -0700 From: David Hedbor <david@hedbor.org> Subject: more patches Ok, another thing I discovered when porting prboom to the Zaurus - mouse events weren't rotated when the screen was (i.e you got incorrect events there). This is now fixed. Also noticed that SDL_WarpMouse isn't handled correctly, but I haven't looked at fixing that yes.
