 Display all the fonts.

 This sketch uses the GLCD (font 1) and fonts 2, 4, 6, 7, 8
 
 Make sure all the required fonts are loaded by editting the
 User_Setup.h file in the TFT_eSPI library folder.

 If using an UNO or Mega (ATmega328 or ATmega2560 processor) then for best
 performance use the F_AS_T option found in the User_Setup.h file in the
 TFT_eSPI library folder.

 The library uses the hardware SPI pins only:
   For UNO, Nano, Micro Pro ATmega328 based processors
      MOSI = pin 11, SCK = pin 13
   For Mega:
      MOSI = pin 51, SCK = pin 52

 The pins used for the TFT chip select (CS) and Data/command (DC) and Reset (RST)
 signal lines to the TFT must also be defined in the library User_Setup.h file.

 Sugested TFT connections for UNO and Atmega328 based boards
   sclk 13  // Don't change, this is the hardware SPI SCLK line
   mosi 11  // Don't change, this is the hardware SPI MOSI line
   cs   10  // Chip select for TFT display
   dc   9   // Data/command line
   rst  7   // Reset, you could connect this to the Arduino reset pin

 Suggested TFT connections for the MEGA and ATmega2560 based boards
   sclk 52  // Don't change, this is the hardware SPI SCLK line
   mosi 51  // Don't change, this is the hardware SPI MOSI line
   cs   47  // TFT chip select line
   dc   48  // TFT data/command line
   rst  44  // you could alternatively connect this to the Arduino reset
