- The _X_I_n_t_e_r_s_e_c_t_R_e_g_i_o_n function computes the intersection of
- two regions.
-
- The _X_U_n_i_o_n_R_e_g_i_o_n function computes the union of two
- regions.
-
- The _X_U_n_i_o_n_R_e_c_t_W_i_t_h_R_e_g_i_o_n function updates the destination
- region from a union of the specified rectangle and the
- specified source region.
-
- The _X_S_u_b_t_r_a_c_t_R_e_g_i_o_n function subtracts srb from sra and
- stores the results in dr_return.
-
- The _X_X_o_r_R_e_g_i_o_n function calculates the difference between
- the union and intersection of two regions.
-
- The _X_O_f_f_s_e_t_R_e_g_i_o_n function moves the specified region by a
- specified amount.
-
- The _X_S_h_r_i_n_k_R_e_g_i_o_n function reduces the specified region by
- a specified amount. Positive values shrink the size of
- the region, and negative values expand the region.
