Is this true? Although not very clearly specified, the (absolute values of the) WindowsTypographicAscent and WindowsTypographicDescent in the OS/2 table should sum to the em square height, positioning the baseline in the em square. I can't guarantee the general case, but can state that Adobe's OpenType fonts do exactly that. - David Lemon
