AFAIK, no. It might be possible to (ab)use the `vmtx' table to store
the TeX height of the glyph, and to (ab)use a `VORG' table[1] to store
the depth, but since in the future we probably need more data anyway
-- zonal kerning, for example -- I think it's easiest to put
everything in an SFNT table specific to lilypond.

[1] `VORG' exists only for CFF fonts. See the OpenType specs for more
details.
