+ basic graphics primitives (points, lines, circles, etc.). It needs
+ to be paired with a hardware-specific library for each display
+ device we carry (handling the lower-level functions).
+ 
+ Adafruit invests time and resources providing this open
+ source code, please support Adafruit and open-source hardware
+ by purchasing products from Adafruit!
