Okey, I add the accessor functions to afhint.c.

I also made the segment drawing independent of the force autofit mode. I 
found that the segment lines are useful reference with or without 
autofit turned on.

One observation I had is that in order to have the outlines merge with 
the segments into one, I have to

1. turn on force autofit (f)
2. turn of Horizontal and Vertical Hinting (H and V)
3. turn on hinting (h)

Otherwise, there are always some offset between the outlines and the 
segments.
