Understood.

Yes.  Note that cairo_glyph_path() doesn't render anything.  It just adds the
path for the glyphs to context.  If you copy_path then new_path, it's gone.

Yes, that's cairo_new_path().

Yes.  What closing?  There is no closing automatically added.  If you removed
your duplicating hack, it should be just a matter of:

  cairo_glyph_path()
  cairo_stroke()

I still am not sure why you insist that you need special processing :P.
