Upon re-reading your message, I see that you said *minimum* recommended
baseline-to-baseline distance. Didn't quite catch that the first time.

Even so, which TrueType field are you referring to? The OS/2 table
contains 3 fields called typoAscender, typoDescender and typoLineGap.
The sum of these 3 fields gives you the recommended
baseline-to-baseline. The sum of the ascender and descender does not
always give you the em height. So what is your minimum recommended
baseline-to-baseline? Ascender + descender? Or em?
