+ * 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
