  29.      This procedure scans through the structural information maintained by Tk
  30.      to compute the root-window coordinates corresponding to the upper-left
  31.      corner of _t_k_w_i_n's border.  If _t_k_w_i_n has no border, then TTTTkkkk____GGGGeeeettttRRRRoooooooottttCCCCoooooooorrrrddddssss
  32.      returns the root-window coordinates corresponding to location (0,0) in
  33.      _t_k_w_i_n.  TTTTkkkk____GGGGeeeettttRRRRoooooooottttCCCCoooooooorrrrddddssss is relatively efficient, since it doesn't have
  34.      to communicate with the X server.
