DirectionsService provides a callback function. That is the second
parameter of route() method.
The callback function is used for calling DirectionsRenderer to draw
the trip by setDirections().
If you try to setCenter() simultaneously, DirectionsRenderer returns
later and overrides your center. DirectionsRenderer doesn't provide
any event or callback but you can construct a once-only event by:
google.maps.event.addListenerOnce(map, 'idle', function(){
map.setCenter(yourLatLng);
});
Put that inside the callback function. It works quite like
'addoverlay' of v2 GDirections().
