translate coordinates from the window they were received on to the event

	* gtk/gtktooltip.c (find_widget_under_pointer): translate coordinates
	from the window they were received on to the event widget's window;
	correct for no-window widgets after that, bail out on failure.  This
	makes the coordinates given by GtkWidget::query-tooltip truly relative
	to widget->window.  (#435188).

	* gtk/gtkwidget.c (gtk_widget_class_init): update docs for
	GtkWidget::query-tooltip.
