Account for the user dot’s alignment when flying to the initial user location. Previously, during incremental location updates, we relied on a hack in which the edge insets resulted in a 0×0 viewport, forcing the center upward or downward. But flyTo() relies on the viewport’s size to control the trajectory. So instead, all location updates now use a correctly-sized viewport centered on the offset user dot.
Pushed the user dot farther away from the view edges.
Programmatic rotation and compass rotation are now centered on the user dot even if it’s aligned at the top or bottom. Previously, pressing the compass would trigger a rotation centered on the center of the view.
