From eccafb8d815068d908b998bb6c0b581b076dc78f Mon Sep 17 00:00:00 2001
From: Bjørn Lindeijer <bjorn@lindeijer.nl>
Date: Mon, 4 Dec 2006 11:20:54 +0000
Subject: Introduced a new class Viewport which combines the drawing code from
 Engine with the (rather misplaced) input handling from the Gui class. Also,
 it's a Container itself which should allow for extending it to show Guichan
 widgets on map coordinates.
