Or: don’t resume the map until the application has entered the foreground.
UIApplicationWillEnterForegroundNotification is posted before UIApplicationDidBecomeActiveNotification, while the application is still in the background. That caused -createGLView to bail but did not cause the rest of -wakeGL: to bail. We would create the GLKView only after attempting to bind it (a no-op), resulting in a black view.
Fixes#1855.
Defer the creation of EAGLEContext and GLKView and the loading of OpenGL ES extensions. It is GLKView that drives the background crash, and Apple documentation specifically warns not to initialize an EAGLContext in the background. All the while, it should be safe for client code to avail itself of any public methods on MGLMapView.
Fixes#1460.

Rely on mbgl to drive compass rotation for simplicity. Eliminated fall-through from mbgl::MapChangeRegionIsChanging to mbgl::MapChangeRegionDidChange, because is-changing should not cause did-change to be fired.
Fixed a bug in which -[MGLMapView direction] could return 360 instead of 0. Switched to mbgl::util::wrap() for clarity. -updateCompass now relies on -direction to avoid code duplication.
In #1793, I conflated the compass container’s constraints to its parent view with the compass container’s content size constraints, but only in the iOS 7 code path. The result was a crash on launch due to an unprepared view hierarchy.
Fixes#1818.
Instead of transforming between return value and callback, pass
the wrapped callback on to the invoked function as the last argument.
This eliminates the need for multiple invokeWithArgument overloads
and permits invoked functions to be asynchronous.
Whoever determined the boundaries of the District of Columbia did not have fit-to-bounds implementations in mind. With this change, shapes that are not unrotated rectangles fit much, much better.
Also, on iOS 8.0+, use `+[NSLayoutConstraint activateConstraints:]` and `+deactivateConstraints:` to efficiently prevent redundant constraints from lingering.
Fixes#1779.
