gbloice 0:ae3d20db48fc 5 * A library for providing a common base class for Graphics displays
gbloice 0:ae3d20db48fc 6 * To port a new display, derive from this class and implement
gbloice 0:ae3d20db48fc 7 * the constructor (setup the display), pixel (put a pixel
gbloice 0:ae3d20db48fc 8 * at a location), width and height functions. Everything else
gbloice 0:ae3d20db48fc 9 * (locate, printf, putc, cls, window, putp, fill, blit, blitbit)
gbloice 0:ae3d20db48fc 10 * will come for free. You can also provide a specialised implementation
gbloice 0:ae3d20db48fc 11 * of window and putp to speed up the results
