A native is made with a function that makes the control and hooks its
events, and one that puts a value on it. hosted puts it in a view: the
control is made once for its place, given a value only when the view's
value changes, and what it sends while it is given one is dropped. Its
outputs become the app's messages through on-output and view-map, and
may be sent from any thread.
