Centred on 0 degrees it left an Australian looking at their own country
in the bottom-right corner, with the paths to everywhere they work
running off both edges. Centred on their own longitude the same map reads
the way their antenna does: the Americas to the east, Europe and Africa
to the west. Leaflet repeats the world horizontally, so this is a choice
of viewpoint and costs nothing — the tiles either side are the same
world, and unwrapLon already draws the arcs across the seam.
The latitude is damped rather than followed (a station at 69 north
centred on itself would spend half the map on the Arctic), the station's
square arrives after the map is built so it re-centres once when it
lands, and a view the operator has panned to themselves still wins.
