_D_e_s_c_r_i_p_t_i_o_n:

     Usually the plotting device resolution allows us to plot only a
     few points per arc with no difference.

_U_s_a_g_e:

     thinlines(arc, tol)

_A_r_g_u_m_e_n_t_s:

     arc: The original arc definition object, as retuend by
          get.arcdata.

     tol: The theshold we used to define which polygons are 'too
          close'.

_V_a_l_u_e:

     A new arc definition object, usually with less points per arc than
     the original. Notice that no modification is made to the topology
     but the number of vertices is updated in the table related to the
     arc definition.
