|
* 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
