Actually, this class is pure. You can implement the default, noop in
RenderWidgetHostViewBase.
Second thing: we shouldn't need to pass render_host_id/route_id : the view can
get it from the host (GetRoutingID(), GetProcess()->GetID()), and even then, the
view should go back to the host to send the message anyway.
