	* gdk/win32/gdkdisplay-win32.c: Remove the clipboard viewer code.
	It didn't really do anything useful, and was just confusing and
	incomplete. Comments claimed we don't do delayed rendering, but in
	fact we do, for images. (The delayed rendering code has other
	problems, though, see #168173.) The clipboard viewer code was
	probably even buggy (the WM_CHANGECBCHAIN handled didn't propagate
	the message when necessary). It was just test code, it said so in
	a comment. Add something similar back later if necessary.

	(_win32_on_clipboard_change,
	_gdk_win32_register_clipboard_notification): Remove.

	(gdk_display_supports_selection_notification,
	gdk_display_request_selection_notification): Always just return
	FALSE. We didn't generate any GDK_OWNER_CHANGE events anywhere.
