       sub-text of M-text mt, starting at from (inclusive) and ending at to (exclusive) while inheriting all the
       text properties of mt.  mt itself is not modified.

           If the operation was successful, mtext_duplicate() returns a pointer to the created M-text. If an
           error is detected, it returns NULL and assigns an error code to the external variable merror_code.
