/*
Tests string alignment

Normally strings are printed relative to the top left corner but this can be
changed with the setTextDatum() function. The library has #defines for:

TL_DATUM = Top left
TC_DATUM = Top centre
TR_DATUM = Top right
ML_DATUM = Middle left
MC_DATUM = Middle centre
MR_DATUM = Middle right
BL_DATUM = Bottom left
BC_DATUM = Bottom centre
BR_DATUM = Bottom right

 
 Needs fonts 2, 4, 6, 7 and 8

 Make sure all the display driver and pin connections are correct by
 editing the User_Setup.h file in the TFT_eSPI library folder.
