* src/window.c: include unistd.h
(get_child_info): new function (add_to_window_list): get the window's client's pid if possible and assign the window the appropriate group and frame. (add_to_window_list): init intended_frame_number (save_mouse_position): save the position relative to the window (give_window_focus): restore the position relative to the window (set_active_window_body): put the window in the frame contained in intended_frame_number when appropriate. * src/screen.c (screen_find_frame_by_frame): new function (init_screen): add the net_supported atom to the root window. * src/main.c (main): init netwm atoms * src/group.c (groups_find_group_by_group): new function * src/globals.c (_net_wm_pid, _net_supported): new globals * src/data.h (struct rp_window): new field intended_frame_number. (struct rp_child_info): new fields group, frame, screen. * src/actions.c (spawn): call the command directly when new argument, raw, is non zero. all callers updated. (spawn): fill in the frame, group and screen for the child.
