+This is the core graphics library for all our displays, providing a common
+set of graphics primitives (points, lines, circles, etc.).  It needs to be
+paired with a hardware-specific library for each display device we carry
+(to handle the lower-level functions).
+
+Adafruit invests time and resources providing this open source code, please
+support Adafruit & open-source hardware by purchasing products from Adafruit!
