  18.      _p_l_a_n_e     Specifies a clipping plane.  The number of clipping planes
  19.                depends on the implementation, but at least six clipping planes
  20.                are supported.  They are identified by symbolic names of the
  21.                form GGGGLLLL____CCCCLLLLIIIIPPPP____PPPPLLLLAAAANNNNEEEEi where 0 _< i < GGGGLLLL____MMMMAAAAXXXX____CCCCLLLLIIIIPPPP____PPPPLLLLAAAANNNNEEEESSSS.

  23.      _e_q_u_a_t_i_o_n  Returns four double-precision values that are the coefficients

  25.                value is (0, 0, 0, 0).
