From 1b61cc8c69025ddd394401a506b21f16df5d4e6d Mon Sep 17 00:00:00 2001
From: Aaron Griffin <aaron@archlinux.org>
Date: Wed, 24 Jan 2007 03:02:53 +0000
Subject: This mainly deals with code clarity- removing currently unneeded
 optimizations in order to make the code much more readable and
 type-checkable. Every enum in the library now has it's own type that should
 be used instead of the generic 'unsigned char'. In addition, several #define
 statements dealing with constants were converted to enums.
