/*
  This example draws fonts (as used by the Adafruit_GFX library) onto the
  screen. These fonts are called the GFX Free Fonts (GFXFF) in this library.

  Other True Type fonts could be converted using the utility within the
  "fontconvert" folder inside the library. This converted has also been
  copied from the Adafruit_GFX library.

  Since these fonts are a recent addition Adafruit do not have a tutorial
  available yet on how to use the utility.   Linux users will no doubt
  figure it out!  In the meantime there are 48 font files to use in sizes
  from 9 point to 24 point, and in normal, bold, and italic or oblique
  styles.

  This example sketch uses both the print class and drawString() functions
  to plot text to the screen.

  Make sure LOAD_GFXFF is defined in the User_Setup.h file within the
  TFT_eSPI library folder.
