        <para>
            <literal>xrpoly</literal> desenha um polígono regular com
            <literal>n</literal> lados contindo no círculo de diâmetro
            <literal>r</literal> e com a origem do círculo posta em um ponto
            <literal>orig</literal>. <literal>theta</literal> especifica a rotação do
            ângulo em radianos. Esta função utiliza as escalas gráficas
            correntes.
