What is the intended scenario for this function? What type of
application is going to use it?

You can't modify `FT_FaceRec' since it would break ABI. However, you
can add stuff to `FT_Face_InternalRec'; this seems to be sufficient
for your proposal.

If we are going to move properties from `FT_Library' to `FT_Face', I
would rather like to have a generic interface that manages options for
`FT_Face': something like an `FT_Face_Option' function, probably using
the `FT_Parameter' structure so that arbitrary data can be set (and
retrieved).
