Reworked the old "expasion" demo and used Stretch elements instead of expanding Text elements. Renamed the demo to have the word stretch in the name.

Demo Element Justification In A Window Using A Text Element That Expands
How to Justify elements on 1 row to be left, right or left, middle, right
Additionally, locate these buttons at the bottom of the screen
The key concepts to use are the newly added expand_x and expand_y
To get 2 buttons to be all the way to the left and to the far right, then
you want to place a text element between them that expands
If you want a third button that is centered, then add TWO Text elements, one
on each side of the middle one
