An EM QUAD is a square [space] with sides equal to the point size of the
font. An EM SPACE is a horizontal measure, usually equal to the side of an
em quad. In condensed fonts, the em space is sometimes smaller than that,
for aesthetic and readability reasons. In expanded fonts, the em space may
be wider than the standard, for the same reasons.
