<link holes>
1, edge detection
- later find true ho points at the same angular pos with the hit edge points.
2. start from angular extremes, find smallest angular pie to hit on the edge of the opposite ho
3. determine clockwiseness
- cross boundary pair: ho(i).bound.r > ho(i+1).bound.r
- here, a(i) should start facing outer circle, move counterclockwise
4. the reason to do a shape-preserving connection:
- if postpone this to a later CC-based approach, i.e., fix CC later instead of fixing holes now, we'll have to search for the problematic position, but with the chain of hos we got, we knew their positions immediately, so now is better than later
5. branch out connection method by size of gap
- gap is bigger than ho size, don't search
