* xterm.h (struct x_display_info): New member, wm_type.
(struct x_output): New members, expected_top/left and
check_expected_move.
* xterm.c (handle_one_xevent): Reset wm_type when ReparentNotify
is received.
(handle_one_xevent): x_check_expected_move renamed from
x_check_fullscreen_move
(x_set_offset): Only add WM decoration sizes to modified_top/left
for X_WMTYPE_A. Set check_expected_move when WM type is unknown.
(x_check_expected_move): Renamed from x_check_fullscreen_move.
Removed fullscreen specific code. Use check_expected_move,
expected_left/top instead. Also, set wm_type.
(x_term_init): Initialize wm_type to unknown.
* frame.c (x_fullscreen_move): Remove addition of WM decoration
sizes to move_x/y.
2003-10-03 Kenichi Handa <handa@m17n.org>
* macterm.c (x_load_font): Clear all members of FONTP before start
