  19.      _S_C_G_e_t_P_a_g_e_S_i_z_e queries a scanner for the size of the scannable area.  _s
  20.      specifies a connection to a scanner previously obtained from a call to
  21.      _S_C_O_p_e_n(3), _S_C_O_p_e_n_F_i_l_e(3), or _S_C_O_p_e_n_S_c_r_e_e_n(3).  _m_e_t_r_i_c is used to specify
  22.      whether the results are required to be in inches (SSSSCCCC____IIIINNNNCCCCHHHHEEEESSSS) or
  23.      centimeters (SSSSCCCC____CCCCEEEENNNNTTTTIIIIMMMM).  _S_C_G_e_t_P_a_g_e_S_i_z_e returns the x and y coordinates
  24.      of the upper left hand corner of the scannable area in _x and _y, and the
