From c581408f028d5b8ceadc53c68d7c1252fbe09e6d Mon Sep 17 00:00:00 2001
From: rcoh <rcoh@mit.edu>
Date: Wed, 22 Dec 2010 14:27:33 -0500
Subject: About halfway done with support for pixel regions.  Modified the
 component registry a bit.  Added support for multiple pixel mappers (and
 along with that, default components). RCOH
