This procedure is invoked to retrieve an option from the
database associated with _t_k_w_i_n's main window. If there is
an option for _t_k_w_i_n that matches the given _n_a_m_e or _c_l_a_s_s,
then it is returned in the form of a Tk_Uid. If multiple
options match _n_a_m_e and _c_l_a_s_s, then the highest-priority one
is returned. If no option matches, then NULL is returned.
TTTTkkkk____GGGGeeeettttOOOOppppttttiiiioooonnnn caches options related to _t_k_w_i_n so that
successive calls for the same _t_k_w_i_n will execute much more
quickly than successive calls for different windows.
