* - added function sed1330_icon to get correct display of full blocks
* May 2003, Joris Robijn
* - Made bars have spaces between them (I hope people like this)
* December 2006, Benjamin Wiedmann
* - added support for Hitachi SP14Q002 gLCD (320x240) with ccfl inverter
* - built for parport version of this interface: Wallbraun Electronics lcdinterface
* (specifications here: http://wallbraun-electronics.de/produkte/lcdinterface/index.html)
