This adds some stuff to the TTF autohinter implementation. This is
implemented and tested (manually) right now (nothing to show off but..):
Local feature analysis:
- Segment/Serif detection and linking.
Global feature analysis:
- detection of standard stem widths.
General:
- Integration of global analysis in the TTF implementation.
- Basic interface for hinter implementation.
- Glyph decomposition in points and contours (in the hinter).
