- Read the specified tile of data and place up to _s_i_z_e bytes of
- decompressed information in the (user supplied) data buffer.

- The value of _t_i_l_e is a ``raw tile number.'' That is, the caller must
- take into account whether or not the data are organized in 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 does this
- when converting an (x,y,z,sample) coordinate quadruple to a tile number.
- To read a full tile of data the data buffer should be at least as large
- as the value returned by _T_I_F_F_T_i_l_e_S_i_z_e.
-
- The library attempts to hide bit- and byte-ordering differences between
- the image and the native machine by converting data to the native machine
- order. Bit reversal is done if the _F_i_l_l_O_r_d_e_r tag is opposite to the
- native machine bit order. 16- and 32-bit samples are automatically
- byte-swapped if the file was written with a byte order opposite to the
- native machine byte order,

- The actual number of bytes of data that were placed in _b_u_f is returned;
- _T_I_F_F_R_e_a_d_E_n_c_o_d_e_d_T_i_l_e returns -1 if an error was encountered.
