+Ok: Implementing it thusly is not feasible since cursor movement gets
+hackish. We use MathAtom only as a wrapper around MathInset * with value
+semantics.
+
+The MathAtom owns the MathInset * and is responsible for proper cloning and
+destruction. Every MathInset * should be put into a MathAtom after its
+creation as soon as possible.
