Indeed, the structures have been defined already in tttypes.h, but
there is no code which uses it.  David?

We are all busy people, doing FreeType as our hobby, and adapting
contributed code to FreeType is much easier and less time-consuming
than developing from scratch.  We would be glad if you can add EBSC
support, or make suggestions how it shall be implemented.  It seems
that your AASB is related to this -- maybe the effort to add this to
FreeType is not too difficult.
