Entering user tracking mode at launch now zooms in and shows the user dot or user puck. The user dot’s heading indicator now points in the correct direction during the animation to the initial location. Course changes are reflected immediately even in the absence of location changes.
Fixes#1145.
When a targetCoordinate is specified in course tracking mode, the map automatically resizes the viewport to show both the user puck and the target, one at the top and the other at the bottom. The user puck now rotates its arrow in the course direction, no longer assuming that the viewport is facing the same way as the course.
Renamed -metersPerPixelAtLatitude: to -metersPerPointAtLatitude:, leaving the old name as a deprecated alias. In Cocoa Touch terminology, “point” is the visual unit backed by pixels.
