/*
	driver quickly hacked together from a chinese sourcecode that came
	with the board and existing ili9320 code by Chris van Dongen (sjaak)
	(sjaak2002 at msn.com)
	
	Also added rotation for 180 and 270 degrees and minor tweaks to
	setcursor
	
	Added code comes without warranty and free bugs. Feel free to use 
	or misuse the added code :D
