Part of Adafruit's GFX graphics library. Originally this class was written to handle a range of color TFT displays connected via SPI, but over time this library and some display-specific subclasses have mutated to include some color OLEDs as well as parallel-interfaced displays. The name's been kept for the sake of older code.
