  77.           The _X_t_G_e_t_S_e_l_e_c_t_i_o_n_V_a_l_u_e function requests the value of the
  78.           selection that has been converted to the target type. The
  79.           specified callback will be called some time after
  80.           _X_t_G_e_t_S_e_l_e_c_t_i_o_n_V_a_l_u_e is called; in fact, it may be called
  81.           before or after _X_t_G_e_t_S_e_l_e_c_t_i_o_n_V_a_l_u_e returns.
  82.  
  83.           The _X_t_G_e_t_S_e_l_e_c_t_i_o_n_V_a_l_u_e_s function is similar to
  84.           _X_t_G_e_t_S_e_l_e_c_t_i_o_n_V_a_l_u_e except that it takes a list of target
  85.           types and a list of client data and obtains the current
  86.           value of the selection converted to each of the targets.
  87.           The effect is as if each target were specified in a separate
  88.           call to _X_t_G_e_t_S_e_l_e_c_t_i_o_n_V_a_l_u_e.  The callback is called once
  89.           with the corresponding client data for each target.
  90.           _X_t_G_e_t_S_e_l_e_c_t_i_o_n_V_a_l_u_e_s does guarantee that all the conversions
  91.           will use the same selection value because the ownership of
  92.           the selection cannot change in the middle of the list, as
  93.           would be when calling _X_t_G_e_t_S_e_l_e_c_t_i_o_n_V_a_l_u_e repeatedly.
