I think it's fine for it to be offset; Myles said he did this
so that it would not be possible to incorrectly rotate it 180deg.

We just need to make sure that the glyph edges fall on 1/5th-em
(or at the very least, 1/10th-em) boundaries.

The intent was just to update Ahem; this would be version 4.
I think it's fine. :)

This can be easily tested by using the square glyphs: if they are not
aligned correctly, they will not line up. :)
