* out whether a glyph gets shifted vertically, but this is something I
* would like to avoid if not really necessary.
*
* Note that we don't follow this logic for the default coverage.
* Complex scripts like Devanagari have mandatory GPOS features to
* position many glyph elements, using mark-to-base or mark-to-ligature
* tables; the number of glyphs missed due to condition (b) would be far
* too large.
