Subject: [PATCH 2/6] Improvements to support point generator
- Separate the 3 bands -- dangling, sloping and full overhanging -- regions and handle them with different support force deficits.
- Use a heuristic for overhanging edges to increase the number of support points generated for them
- Try to make overhangs and slopes deficit depend on stable area.
