From 84b9aa2e5eef8a8707133ab421aa6cab83761f97 Mon Sep 17 00:00:00 2001
From: Shon Ferguson <shonferg@users.sourceforge.net>
Date: Mon, 7 May 2007 23:19:12 +0000
Subject: [PATCH] Added functions to NiImage and NiTextureProperty to allow
texture name to be manipulated in <= 3.1 files. Updated ComplexShape to take
the above objects into account when deciding whether to include UV
coordinates.
