	Once again rework Win32 window decoration code. Doesn't break
	#104514. The dialogs in gtk-demo now have the same decorations and
	behaviour as on X11. Tried to fix #322516 but it seems very hard
	to make the trivial sample program there behave as expected. OTOH,
	simply moving the gtk_window_decorate() call in the #322516 sample
	program after the call to gtk_widget_show() helps...

	* gdk/win32/gdkwindow-win32.c (set_or_clear_style_bits): Revert to
	the correct semantics. Each call to gdk_window_set_decorations()
	which calls this function is supposed to affect all decorations.

	(decorate_based_on_hints): New function, looks at both geometry
	hints and type hint and sets window decorations based on
	that. Consolidate code from gdk_window_set_geometry_hints() and
	gdk_window_set_type_hint() here.

	(gdk_window_set_geometry_hints, gdk_window_set_type_hint): Call
	decorate_based_on_hints().
