From 685b33980cc7a346574b24732464f0cbe3115a1f Mon Sep 17 00:00:00 2001
From: Dan Goodliffe <dan@randomdan.homeip.net>
Date: Wed, 15 Nov 2023 01:29:24 +0000
Subject: Switch to millimeters for spatial units

Mostly a case of changing far too many magic numbers, something else to
fix I guess. I probably missed something. Also there's some hackery when
loading 3D models, which are still assumed to be in metres.
