From 355c6bfe3cb41adf8b34f0ebf8f2cd3759ce1002 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <ben@decadent.org.uk>
Date: Thu, 15 Dec 2005 00:43:33 +0000
Subject: [PATCH] Disabled scroll bars (though this doesn't seem to work in
 every case). Moved tweaking of page settings so it's done at the right time
 whether in preview or processing mode.
