	Bug 113310.

	* gdk/x11/gdkwindow-x11.c (_gdk_x11_window_tmp_{un|re}set_bg):
	New functions that can do a recursive unset/reset bg.

	* gdk/x11/gdkgeometry-x11.c: Remove
	gdk_window_tmp_{un|re}set_bg().

	* gdk/x11/gdkwindow-x11.c (pre_unmap, post_unmap): New functions
	called before and after unmapping a window. They unset the
	background of all other windows to prevent flicker from the X
	server repainting the background. post_unmap() also invalidates
	the parent of the unmapped window to draw it without roundtrips.

	* gdk/x11/gdkwindow-x11.c (show_window_internal): Unset
	background of newly mapped windows and all desendants to prevent
	flicker.
