    Think the compiled numbers are correct but available is incorrect. Paul just recently posted about that: https://forum.pjrc.com/threads/54711-Teensy-4-0-First-Beta-Test?p=211545&viewfull=1#post211545

    Good question - probably update SPITFT if Adafruit is amiable to the changes for the Teensies. GFX seems to be incorporated into most of the libraries I have seen.
