- Added the class `CGAL::Surface_mesh_simplification::GarlandHeckbert_plane_and_line_policies`, which provides improved output for `CGAL::Surface_mesh_simplification::edge_collapse`.
- That class works the same as previous `GarlandHeckbert_policies`
- Its constructor takes a `Mesh` and an optional `double` parameter specifying the weight of the line policy relative to the plane policy (default: 0.01).
- `CGAL::Surface_mesh_simplification::GarlandHeckbert_policies.h` is now an alias of `CGAL::Surface_mesh_simplification::GarlandHeckbert_plane_plus_line_policies.h` and is no longer deprecated.
