  screen.

  The _C_e_l_l_s_O_f_S_c_r_e_e_n macro returns the number of	colormap cells in the default
  colormap of the specified screen.

  The _D_e_f_a_u_l_t_C_o_l_o_r_m_a_p_O_f_S_c_r_e_e_n macro returns the	default	colormap of the
  specified screen.

  The _D_e_f_a_u_l_t_D_e_p_t_h_O_f_S_c_r_e_e_n macro returns the default depth of the root window
  of the specified screen.

  The _D_e_f_a_u_l_t_G_C_O_f_S_c_r_e_e_n	macro returns the default GC of	the specified screen,
  which	has the	same depth as the root window of the screen.

  The _D_e_f_a_u_l_t_V_i_s_u_a_l_O_f_S_c_r_e_e_n macro returns the default visual of	the specified
  screen.

  The _D_o_e_s_B_a_c_k_i_n_g_S_t_o_r_e macro returns _W_h_e_n_M_a_p_p_e_d, _N_o_t_U_s_e_f_u_l, or _A_l_w_a_y_s, which
  indicate whether the screen supports backing stores.

  The _D_o_e_s_S_a_v_e_U_n_d_e_r_s macro returns a Boolean value indicating whether the

  specified screen.

  The _E_v_e_n_t_M_a_s_k_O_f_S_c_r_e_e_n	macro returns the root event mask of the root window
  for the specified screen at connection setup.

  The _H_e_i_g_h_t_O_f_S_c_r_e_e_n macro returns the height of the specified screen.

  The _H_e_i_g_h_t_M_M_O_f_S_c_r_e_e_n macro returns the height	of the specified screen	in
  millimeters.

  The _M_a_x_C_m_a_p_s_O_f_S_c_r_e_e_n macro returns the maximum number	of installed color-
  maps supported by the	specified screen.

  The _M_i_n_C_m_a_p_s_O_f_S_c_r_e_e_n macro returns the minimum number	of installed color-
  maps supported by the	specified screen.

  The _P_l_a_n_e_s_O_f_S_c_r_e_e_n macro returns the number of planes	in the root window of
  the specified	screen.

  The _R_o_o_t_W_i_n_d_o_w_O_f_S_c_r_e_e_n macro returns the root	window of the specified
  screen.
