Yes, I think so, assuming that you are using the FreeType library out
of the box.

There is no such functionality anymore, and noone has ever requested
it.  May I suggest the following approach: Simply assume that FreeType
does the right thing.  In case it doesn't, please open a bug report,
ideally providing a patch.  It should be straightforward to add a new
function to the API, but I would prefer if you could provide an OS/2
specific version of `ftsystem.c' (and probably `ftdebug.c' also).
