todo:
- debug coplanar color for edges for some cases
- remove empty groups (text)
- abort if 0 faces
- give hints for joinery preparations (apply transform, ungroup, ...)
- update documentation accordingly
- make angleRange global for complete unfolding (to match glue pairs between multiple unfoldings)
- add angleRange to stats
