From 77a60673ef970ec32fc2e4db09aa5ac534481c8d Mon Sep 17 00:00:00 2001
From: Nicola Mettifogo
Date: Wed, 2 Jul 2008 01:41:08 +0000
Subject: - Changed labels to be GfxObj's, thus removing the Label object
 altogether. - Changed Item's to be almost GfxObj's, since ownership and
 destruction of underlying resource is an issue here (got to think some more
 about it).
