Date: Mon, 29 Dec 2008 23:29:52 +0100 From: Couriersud Subject: SDL1.3: Some X11 diffs The attached diff fixes the following issues in the X11 backend: a) When calling resize, actually a move was performed. This has been corrected. b) DisplayHeight and DisplayWidth do not return up-to-date information after a modeswitch using the xrandr code, which I enabled in x11_modes.c Height and width are now queried from the root window and all occurrences of DisplayHeight and DisplayWidth changed.
