WINGs/wview_wl: recursively redisplay children in wl_redisplay 

wl_redisplay fills the view's background then paints widget content
via expose, but never re-composited child views. Children painted
earlier were erased by the parent's background fill. Now recursively
calls wl_redisplay on all mapped+realized children after the parent's
expose handler, so the full widget tree composites bottom-up.
