What's remarkable about this program is that the animation is created by updating individual Text Elements going
down the window, one line at a time, every time through the loop. That's 48 lines of text every time. Rough
timing shows an animation of more than 10 fps when running any of the PySimpleGUI ports.
Also added onto this are a spinner and a slider. They do essentially the same thing, enable a pair of parameters
to be modified on the fly.
