From d61cff7a7976cd9097e5c3634ae4b1be64f736c3 Mon Sep 17 00:00:00 2001
From: Andrew Hannam <andrewh@inmarket.com.au>
Date: Sun, 5 Aug 2012 00:46:43 +1000
Subject: Many changes including scaled fonts.
Scaled fonts (independantly in x & y direction) based on normal sized
font. Effectively double sized and double height same width fonts come
free (or triple etc).
New routine for sending low level drivers hardware commands eg backlight
off/on
Power and Orientation moved to new routine.
Clean up on files to simplify low level driver file overheads.
