  17.      Read the contents of the specified tile into the (user supplied) data
  18.      buffer.  Note that the value of _t_i_l_e is a ``raw tile number.''  That is,
  19.      the caller must take into account whether or not the data is organized in
  20.      separate planes (_P_l_a_n_a_r_C_o_n_f_i_g_u_r_a_t_i_o_n=2).  _T_I_F_F_C_o_m_p_u_t_e_T_i_l_e automatically
  21.      does this when converting an (x,y,z,sample) coordinate quadruple to a
  22.      tile number.  To read a full tile of data the data buffer should
  23.      typically be at least as large as the value returned by _T_I_F_F_T_i_l_e_S_i_z_e.
