+TFT Library
+============
+
+An Arduino library for the Arduino TFT LCD screen.
+
+This library enables an Arduino board to communicate with an Arduino TFT LCD screen. It simplifies the process for drawing shapes, lines, images, and text to the screen.
+The Arduino TFT library extends the Adafruit GFX, and Adafruit ST7735 libraries that it is based on. The GFX library is responsible for the drawing routines, while the ST7735 library is specific to the screen on the Arduino GTFT. The Arduino specific additions were designed to work as similarly to the Processing API as possible.
+
+Onboard the screen is a SD card slot, which can be used through the SD library.
+
+The TFT library relies on the SPI library for communication with the screen and SD card, and needs to be included in all sketches.

+ * This library can work with or without the presence of an SD

+ * 
+ * The presence of the SD library is detected by looking at the

+ * 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.
