From 2758b5a2b9dcaecfb6fd0430875075b4a9eadb02 Mon Sep 17 00:00:00 2001
From: lewster32 <septimus@rotates.org>
Date: Mon, 18 Aug 2014 17:42:58 +0100
Subject: [PATCH] Added depth sorting methods to Projector (simple and
 topological). Added derived bounding cube to IsoSprites. Removed tweaks to
 IsoArcade collision handlers to make it act like original. Fixed Octree and
 QuadTree.
