	* gtk/gtkdnd.c (gtk_drag_find_widget): Optimization -
	when we've already found a widget, skip all checks
	for subsequent children.

	* gtk/gtkdnd.c (gtk_drag_find_widget): Checked for
	!MAPPED, not !VISIBLE, since a widget (like a notebook
	page), can be VISIBLE, but !REALIZED or !MAPPED.

	* gtk/gtkdnd.c (gtk_drag_find_widget): Use forall(),
	not foreach().
