    Adapted from code originally from this fantastic repository:
    https://github.com/nycynik/ascii-font-processor
    Thank you nycynik for a fantastic headstart
    
    If you are running PySimpleGUI before verion 4.35.0.11, then you'll get an error
    message saying there is a problem with:  bound method Multiline.__del__
    It's because a newer parm is used in this code.  It'll all still work just fine with this error.
    
    This demo has an interesting little trick.  If the window is resized, then it
    will use the new size of the Multiline element to compute the numiber of characters
    wide the Multiline has to work with.  This number is passed to the figlet renderer.
