/***************************************************
Arduino TFT graphics library targetted at the UNO
and Mega boards.
This library has been derived from the Adafruit_GFX
library and the associated driver library. See text
at the end of this file.
This is a standalone library that contains the
hardware driver, the graphics funtions and the
proportional fonts.
The larger fonts are Run Length Encoded to reduce
their FLASH footprint.
