| simon | 0:f42b25503fd1 | 5 | * A library for providing a common base class for Graphics displays |
| simon | 0:f42b25503fd1 | 6 | * To port a new display, derive from this class and implement |
| simon | 0:f42b25503fd1 | 7 | * the constructor (setup the display), pixel (put a pixel |
| simon | 0:f42b25503fd1 | 8 | * at a location), width and height functions. Everything else |
| simon | 0:f42b25503fd1 | 9 | * (locate, printf, putc, cls, window, putp, fill, blit, blitbit) |
| simon | 0:f42b25503fd1 | 10 | * will come for free. You can also provide a specialised implementation |
| simon | 0:f42b25503fd1 | 11 | * of window and putp to speed up the results |
