IMO there is no vertical advance width, as long as the Type 1 charstring
starts with 'hsbw' (as opposed to 'sbw'). Hence freetype should not
return one for these fonts, which indeed use 'hsbw'.

The used metrics seem to be the ones from the intended glyphs. In case
this helps locating the problem ...
