  18.      The following routines are provided for client-control of the I/O buffers
  19.      used by the library.  Applications need never use these routines; they
  20.      are provided only for ``intelligent clients'' that wish to optimize
  21.      memory usage and/or eliminate potential copy operations that can occur
  22.      when working with images that have data stored without compression.

  24.      _T_I_F_F_R_e_a_d_B_u_f_f_e_r_S_e_t_u_p sets up the data buffer used to read raw (encoded)
  25.      data from a file.  If the specified pointer is NULL (zero), then a buffer
  26.      of the appropriate size is allocated.  Otherwise the caller must
  27.      guarantee that the buffer is large enough to hold any individual strip of
  28.      raw data.  _T_I_F_F_R_e_a_d_B_u_f_f_e_r_S_e_t_u_p returns a non-zero value if the setup was
  29.      successful and zero otherwise.
  30.  
  31.      _T_I_F_F_W_r_i_t_e_B_u_f_f_e_r_S_e_t_u_p sets up the data buffer used to write raw (encoded)
  32.      data to a file.  If the specified _s_i_z_e is -1 then the buffer size is
  33.      selected to hold a complete tile or strip, or at least 8 kilobytes,
  34.      whichever is greater.  If the specified _b_u_f_f_e_r is NULL (zero), then a
  35.      buffer of the appropriate size is dynamically allocated.
  36.      _T_I_F_F_W_r_i_t_e_B_u_f_f_e_r_S_e_t_u_p returns a non-zero value if the setup was successful
  37.      and zero otherwise.
