Notice the same starting row is used for all "EXAMPLE" characters, and
they are all aligned on the same baseline (or bottom), regardless of
expanded or compressed parameters. The string rotates around the point of
intersection of the starting row and columns shown by the "pinwheel" E. A
rotated 10 cpi character establishes the baseline for all character sizes.
