- Changed triangulation of volume polygons to Delaunay to avoid degenerate tris when possible.
- Added ability to set degenerate tri normals to neighbor normal to avoid creating nonplanar volume polygons if degenerate tris do appear.
- Created a path to use FPolys instead of bsp nodes to convert from volumes, as nodes get broken up arbitrarily.
- Gave volume conversion the ability to preserve group boundary edges.
- Changed PlanarFlipsOptimization to correctly deal with degenerate tris, and to respect group boundaries.
- Added legacy cleanup code that Ryan ported to make volume faces convex.
- Changed our version of the convexity code to avoid arbitrary precision cutoff, and to remove one of the places we were arbitrarily throwing away colinear verts.
- Changed on-the-fly conversion options to not try to fill cracks, as this seems to worsen any problems further.
