when using cfg.numvertices (e.g. in prepare_singleshell, or prepare_mesh) there are different algorithms used for resampling the original mesh. E.g. in prepare_mesh_headshape it uses MSPHERE, whereas in ft_prepare_mesh when basedonsphere=yes it also can use ICOSAHEDRON. there should be a consistent and high quality implementation for resampling triangulated meshes.

looking at the code and bug 1646, it appears that the meshing can still be inconsistent over different functions. to be discussed

Robert, during the bug binge you mentioned this might still be an actual issue. Please check/specify what actions need be taken.
