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

     Control parameters associated with the autocrop algorithm.

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

     polyAutocrop(tt1 = NULL)

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

     tt1: a Tk toplevel widget.

_D_e_t_a_i_l_s:

     Requires access to the following components within 'srvy.dat':
     'data.raw', 'win.width', 'csi', and 'vars[2:3]'.  The default
     maximum arc length for a cell is determined from the maximum
     length within the Delaunay triangulation mesh  and an interation
     limit for the algorithm.  Entering arc lengths less than the
     default value  will reduce the polygons size.

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

     A polygon of class 'gpc.poly'.

_A_u_t_h_o_r(_s):

     Fisher, J. C.
