        <para>
            This routine can be used to delete a graphics entity identified
            by the handle given as argument. In this case, All children of
            this graphics entity will be deleted.
            Without any argument <literal>delete</literal> removes the
            current entity. With <literal>"all"</literal> argument it deletes
            all the entities of the current figure.
        </para>
        <para>
            The <literal>"callback"</literal> argument is not yet handled.
