	* gdk/x11/gdkgeometry-x11.c (gdk_window_compute_position):
	Clamp max window width/height to 32767, not 32768 since
	we have to be able to deal with a dx/y of -32768 without
	getting a width of 65536 when guffaw scrolling.

	* gdk/x11/gdkgeometry-x11.c: Implement gdk_window_scroll()
	for the guffaw scrolling case, fixing some problems with
	copy-area case as well. Fix BadValue bug with moving windows
	by large amounts.

	* gdk/x11/gdkgeometry-x11.c (gdk_window_clip_changed): Update
	clip in window structue before calling gdk_window_invalidate_region
	since that trims new invalidations to the window's visible
	region.

	* gdk/x11/gdkwindow-x11.c (gdk_window_set_static_gravities):
	Really set the static window gravity on the children, not
	repeatedly on the window.

	* gtk/testgtk.c: Add a torture test for big windows and
	gdk_window_scroll().
