* Standardize on std::exception_ptr as the error representation
(fixes#2854).
* Don't format textual strings at the error source; pass on the
constituent data via observer method parameters instead.
* Use the null object pattern to simplify observer notification code.
* Further refactoring for ResourceLoading tests.
Renamed -metersPerPixelAtLatitude: to -metersPerPointAtLatitude:, leaving the old name as a deprecated alias. In Cocoa Touch terminology, “point” is the visual unit backed by pixels.
Greatly simplified conversions between zoom level and altitude. Adjusted field of view to more closely match MapKit. Conversions are now well within the same order of magnitude as MapKit at all latitudes.
Fixes#2266.
For consistency with -setCamera:…, a duration of 0 jumps instantaneously to the new location, while a negative value uses the distance-dependent default.
Due to the produced curve and applied easing, flyTo() doesn’t model a parabola or ballistic trajectory, but it does simulate powered flight to some extent.

Setting the viewport size from the main thread has no affect
on Linux and thus, the map doesn't scale. We now set the
viewport size on the beforeRender() hook that gets called
from the Map thread.
Exposed Map::addCustomLayer() publicly as an undocumented, block-based API. This change avoids the terms “layer”, “initialize”, “render”, and “altitude” because they overload existing terminology in the SDK, UIKit, or MapKit. (“Layer” is qualified as “style layer”.) There are outstanding questions about ARC memory management, but this approach works in both Objective-C and Swift for pure OpenGL programming.
Added a demo to iosapp that draws a green layer below any labels in Mapbox Streets.
