Owen Taylor 9bedbf662d Use asynchronously _gdk_x11_set_input_focus_safe to avoid having to trap
Fri Jul  4 15:57:52 2003  Owen Taylor  <otaylor@redhat.com>

	* gdk/x11/gdkevents-x11.c (gdk_wm_protocols_filter):
	Use asynchronously _gdk_x11_set_input_focus_safe
	to avoid having to trap errors and XSync().

	* gdk/x11/gdkwindow-x11.c (gdk_window_focus): Use
	_gdk_x11_set_input_focus_safe() here as well.

	* gdk/x11/gdkevents-x11.c (gdk_check_wm_state_changed):
	Rework handling of property notifies on _NET_WM_STATE
	so that we ignore _NET_WM_DESKTOP notifies unless we
	really care.

	* gdk/x11/gdkimage-x11.c (gdk_image_check_xshm): Use
	XShmQueryExtension() rather than XQueryExtension() to
	avoid extra rountrip.

	* gdk/x11/gdkwindow-x11.c (_gdk_windowing_window_init):
	Remove unused call to XGetWindowAttributes()

	* gdk/x11/gdkdisplay-x11.c (gdk_display_open): Remove
	unused call to XGetKeyboardControl().

	* gdk/x11/gdkdisplay-x11.c gdk/gdk.def (gdk_display_flush):
	Add (#99571)

	* gdk/win32/gdkevents-win32.c gdk/linux-fb/gdkevents-fb.c
	No-op implementations of gdk_display_flush().

	* gdk/gdkwindow.c (gdk_window_process_all_updates): Use
	gdk_display_flush() rather than gdk_flush() to avoid
	XSync().

	* gdk/x11/gdkwindow-x11.c (update_wm_hints)
	gdk/x11/gdkwindow-x11.h: Centralize all handling of WM_HINTS here
	so that we don't have to get the property back from the server.

	* gdk/x11/gdkwindow-x11.c (show_window_internal): Store
	the serial of when we map a toplevel to allow optimizing
	out notifies on _NET_WM_STATE/_NET_WM_DESKTOP.

	* gdk/x11/gdkevents-x11.c (gdk_event_translate): Don't
	XTranslateCoordinates() for override-redirect windows.

Fri Jul  4 15:59:27 2003  Owen Taylor  <otaylor@redhat.com>

	* gdk/x11/gdkwindow-x11.c (gdk_window_set_group): Remove comment
	about setting window group after the window is mapped from docs
	- nothing the ICCCM forbids that.

	* gdk/x11/gdkcursor-x11.c (gdk_display_get_maximal_cursor_size):
	Fix g_return_val_if_fail() in void return function.

	* configure.in: Fix misplaced comma that was resulting
	in XShm always being disabled.
