Travis is inconsistently failing the following tests, so let's
temporarily disable them.
- `testDirectionSet`
- `testCompassTap`
- `testDirectionReset`
- `testCenterSet`
- `testDelegateRegionDidChange`
It bears repeating that these tests _only_ fail on Travis, running them
locally has always passed.
Fixes#2347
I thought that the tests were bypassing the permissions dialog, but it turns out that was only half correct: we were not actually asking for `always` location permission in MBGL.
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.
Added a bunch of functions to work with MGLCoordinateBounds in a separate header analogous to MKGeometry.h. Added resolution-independent tests for common fit to bounds scenarios.
- Adds testDelegatesStartStopLocatingUser: Tests mapViewWillStartLocatingUser and mapViewDidStopLocatingUser delegate methods
- Adds testUserTrackingModeFollow
- Adds testUserTrackingModeFollowWithHeading (disabled because of library bug)
Fakes user location via swizzled CLLocationManager and hard-coded mock coordinates and heading.
