Lazy "Place on face" gizmo update.
Caching of MeshObject::raw_mesh_bounding_box() for the object size display.
ModelObject::bounding_box(), raw_mesh_bounding_box(), full_raw_mesh_bounding_box() will not copy the mesh.
TriangleMesh::transformed_bounding_box(const Transform3d &trafo) will not copy the mesh data.
get_options_for_bundle() will not return reference to temp value
is_splittable() calls cheap mesh.has_multiple_patches()
