- The _X_m_b_D_r_a_w_T_e_x_t and _X_w_c_D_r_a_w_T_e_x_t functions allow complex
- spacing and font set shifts between text strings. Each
- text item is processed in turn, with the origin of a text
- element advanced in the primary draw direction by the
- escapement of the previous text item. A text item delta
- specifies an additional escapement of the text item draw-
- ing origin in the primary draw direction. A font_set mem-
- ber other than _N_o_n_e in an item causes the font set to be
- used for this and subsequent text items in the text_items
- list. Leading text items with a font_set member set to
- _N_o_n_e will not be drawn.
-
- _X_m_b_D_r_a_w_T_e_x_t and _X_w_c_D_r_a_w_T_e_x_t do not perform any context-
- dependent rendering between text segments. Clients may
- compute the drawing metrics by passing each text segment
- to _X_m_b_T_e_x_t_E_x_t_e_n_t_s and _X_w_c_T_e_x_t_E_x_t_e_n_t_s or _X_m_b_T_e_x_t_P_e_r_C_h_a_r_E_x_-
- _t_e_n_t_s and _X_w_c_T_e_x_t_P_e_r_C_h_a_r_E_x_t_e_n_t_s. When the _X_F_o_n_t_S_e_t has
