We now drive rendering from the main thread calling renderSync(),
but if we do it just after we set the style URL it will assert
because renderSync() expects the style to be fully loaded.
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.
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.
Each side of the bounding box is specified independently, allowing more flexibility than the offset + padding construct supported in mapbox/mapbox-gl-js’ Camera.
The new implementation is now public and takes advantage of MGLCoordinateBounds. It is re-ported from `Camera.prototype.fitBounds()` in mapbox/mapbox-gl-js to ensure correct behavior. A new function, MGLCoordinateBoundsMake(), makes it easier to create an MGLCoordinateBounds for use with this method.
Listening to both `locationManager:didChangeAuthorizationStatus:` and `locationManager:didFailWithError:` delegate methods is unnecessary. Setting `showsUserLocation = NO` in the first means that the second never gets called and our `mapView:didFailToLocateUserWithError:` delegate method never gets called.
For now we set the FileSource for the Worker context
but in the future after fixing #1664 we can assert()
that FileSource are set only for the Map thread context.
Do not use the Environment anymore. The Environment ID is not
really necessary anymore as we are forwarding exceptions to the
main thread, so we always know which Map object triggered the
error.
mbgl::Thread will keep a ThreadContext for each running instance
in a thread_local so we don't need to lookup a man in the Environment
every time we need some info about the current thread.
This patch is moving the ::currentlyOn check used on Debug build from
the Environment class to the ThreadContext.
