Yeah.  I was thinking of storing it internally in hundredths of em's or
something.  My book claims that machines traditionally divided the EM
into eighteen, thirty-six, or fifty-four subparts.  I didn't seem to do
a good job explaining this.

Additionally, I don't know if we want to distinguish between height and
width of a font, as an 'em' is technically only a horizontal unit of
measure.  Adding two font-based units seems to be possibly too
confusing, though.

Thanks,
