This is not possible.  The stroker broadens the outline, while during
normal rendering the outline gets filled.

Why should FreeType use it internally?

Do you really expect that I speculate on your mental state? :-)

To be serious: Can you think of a reason why you haven't found it in
the docs?  Terminology problems?  Bad organization?

I'm not aware of *fundamental* problems.  You get bad results if the
strokes become too broad.

Oh!  I would have never come to that conclusion.  Actually, I consider
the programs in the ft2demos bundle -- especially ftview -- as a kind
of `reference implementation', which is neither very fast nor very
effective, but which demonstrates the basic usage of the library.

Can you contribute a patch which does this?
