[This is not a blocking comment]
@SteveL-MSFT I just noticed that in the switch (alignment) block below, addPadding is checked only when padding for left alignment, not when padding for center alignment. This is not in the same pattern as in the switch (alignment) block in if (currentValueDisplayLength < width). Just want to bring it up so you can take a another look to see if it's intended.

Good catch, let me check this. I'll add an extra test for truncation.
