From 5b2cba17aa95ececfdb6a498540de4dfa215e920 Mon Sep 17 00:00:00 2001
From: Jens Arnold <amiconn@rockbox.org>
Date: Wed, 16 Nov 2005 21:09:23 +0000
Subject: Changed the LCD_COLOR pixel value format to packed RGB (unsigned
 int). Now all LCDs with depth > 1 use the same datatype. Added macros for
 easy pixel value definition.
