From 56a59e2e51d0cbe93ce16253e52a6421b0168c06 Mon Sep 17 00:00:00 2001
From: Simon Tatham <anakin@pobox.com>
Date: Wed, 28 Apr 2004 17:21:57 +0000
Subject: Introduce diagonal movement keys on the numeric keypad, and use them
 as an alternative control method in Cube. (This was a bit of hassle in the
 Windows front end; I also introduced a debugging framework and made
 TranslateMessage conditional.)
