/* mbed GraphicsDisplay Display Library Base Class
* Copyright (c) 2007-2009 sford
* Released under the MIT License: http://mbed.org/license/mit
*
* A library for providing a common base class for Graphics displays
* To port a new display, derive from this class and implement
* the constructor (setup the display), pixel (put a pixel
* at a location), width and height functions. Everything else
* (locate, printf, putc, cls, window, putp, fill, blit, blitbit)
* will come for free. You can also provide a specialised implementation
* of window and putp to speed up the results
