navview::draw (Waypoints, trail back, Nearby, a message's location) shows a
dial beside the lines, or under them on a tall screen (portrait e-ink) where
that makes it larger: with a course a turn dial (the top is where you're
heading, the arrow points at the target, "Turn R 55"), without it the compass
rose. The 4.2" screens keep theirs. On a short screen (the 64 px OLED) the
gap under the distance and the pitch of the lines give way so the ETA is not
cut off at the bottom.
sim_nav_waypoint() opens a waypoint's navigate view from the simulator page.
