-/* Derived from the 2011 IOCCC submission by peter.eastman@gmail.com

- * --
- * Public Domain -- but you're looking at this for ideas of techniques
- * and methods, not trying to cut&paste an entire application, anyway.
- * --
- * When you need to blit an entire screenfull of data to an LCD
- * display, the basic idea is to exploit the auto-increment feature of
- * the display controller when it writes to screen memory. You start
- * by resetting the 'cursor' to the 0,0 position, and then stream
- * width*height pixels out.
