From a79dc877615c2af571bf0416dd2867c000701e7e Mon Sep 17 00:00:00 2001
From: Thomas Martitz <kugel@rockbox.org>
Date: Sun, 11 Oct 2009 12:21:27 +0000
Subject: Add a center flag, next to the rtl flag, for viewports. That results
 in any text being drawn centered. It overrides the RTL flag if set.

Simplify splashes and time menu by using it.
