Graphics test for Adafruit ILI9341 library with HW SPI - ( for 320x240 ebay/aliexpress breakout with SD, TFT and touch )

	/***************************************************
	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)
	Adafruit invests time and resources providing this open source code,
	please support Adafruit and open-source hardware by purchasing
	products from Adafruit!

Get moonphase and if it is waxing or waning.

	// Moon age, takes three parameters: the year (4 digits), the month and the day.
	// The function returns fraction full, float 0-1 (e.g. 0 for new, .25 for crescent, .5 for quarter, .75 for gibbous and 1 for full).
	// Also calculates age and age in days. THIS VERSION uses a cosine function to model the illumination fraction.
	// Calculated at noon, based on new moon Jan 6, 2000 @18:00, illumination accurate to about 5%, at least for years 1900-2100.
	// Modified from post at http://www.nano-reef.com/topic/217305-a-lunar-age-function-for-the-arduino/
