From 8292b80eac900ec5dd75d184063b7b35934e800a Mon Sep 17 00:00:00 2001 From: Thorbjørn Lindeijer Date: Sat, 21 Jan 2012 12:30:36 +0100 Subject: Allow resizing of the game in windowed mode Window positions are semi-smartly corrected as a result of the resize. Not supported when using OpenGL on Windows for now.
