には「potm->otmsCapEmHeight = pOS2->sCapHeight」と書いてある。

で、「sCapHeight」を調べたら

This metric specifies the distance between the baseline and the approximate
height of uppercase letters measured in FUnits. This value would normally be specified
by a type designer but in situations where that is not possible, for example when a
legacy font is being converted, the value may be set equal to the top of the unscaled
and unhinted glyph bounding box of the glyph encoded at U+0048 (LATIN CAPITAL
LETTER H). If no glyph is encoded in this position the field should be set to 0.

This metric, if specified, can be used in systems that specify type size by capital height
measured in millimeters. It can also be used as an alignment metric; the top of a drop
capital, for instance, can be aligned to the sCapHeight metric of the first line of text.
