- Fix conversion sometimes making degenerate tris and firing an ensure.
- Fix volume conversion sometimes creating cracks in volumes when dealing with non-convex faces (by deleting necessary colinear verts)
- Make simplification preserve group boundaries when asked.
- Remove colinear verts along group boundaries without losing boundaries when preserving groups.
- Break up faces that have holes into convexes rather than emitting per-triangle faces.
- Make mesh to volume tool use same path for conversion as tool targets, and add controls for preserving groups and simplifying
- Revert to ear clipping if delaunay triangulation fails in converting back from volume
