- This is the core graphics library for all our displays, providing
- 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!

- * This library can work with or without the presence of an SD
- * reading library (to load images). At the moment, only the
- * Arduino SD library is supported; it is included in
- * standard Arduino libraries.
- * 
- * The presence of the SD library is detected by looking at the
- * __SD_H__ preprocessor variable, defined into 
- * Arduino SD library to avoid double inclusion. This means
- * that in order to use the image-related API of Adafruit_GFX,
- * SD.h *must* be included before Adafruit_GFX.
- * 
- * The bottom part of this include file contains the actual image
- * loading code; if it was in a separate .cpp file, there were no
- * way to check if the SD library was present or not.
- * 
- * A partial solution was to include SD.h anyway, see if that works
- * (i.e. it is found in the include search path) and act accordingly.
- * But this solution relied on the preprocessor to issue only a
- * warning when an include file is not found. Avr-gcc, used for
- * Arduino 8-bit MCUs, does that, but the standard gcc-4.4, used for
- * Arduino Due, issues a fatal error and stops compilation.
- * 
- * The best solution so far is to put the code here. It works if this
- * include is used only in one .cpp file in the build (this is the
- * case of most Arduino sketches); if used in multiple .cpp files,
- * the linker may complain about duplicate definitions.
