/***************************************************
This is our GFX example for the Adafruit ILI9341 Breakout and Shield
----> http://www.adafruit.com/products/1651
Check out the links above for our tutorials and wiring diagrams
These displays use SPI to communicate, 4 or 5 pins are required to
interface (RST is optional)
