+ Arduino TFT Bitmap Logo example
+ 
+ This example reads an image file from a micro-SD card
+ and draws it on the screen, at random locations.
+ 
+ In this sketch, the Arduino logo is read from a micro-SD card.
+ There is a .bmp file included with this sketch. 
+ - open the sketch folder (Ctrl-K or Cmd-K)
+ - copy the "arduino.bmp" file to a micro-SD
+ - put the SD into the SD slot of the Arduino TFT module.
+ 
+ This example code is in the public domain.
