When converting a constant NSExpression to an mbgl::Value, turn an NSColor or UIColor into an std::string containing a CSS color string. This allows developers to set an attribute of an MGLFeature to an NSColor or UIColor (rather than a CSS color string, which would be foreign), then use it in an MGLStyleFunction with identity interpolation.
This leverages the work already happening in `mbgl::style::conversion` to convert style functions from style-spec definitions into `mbgl::style::{Camera,Source,Composite}Function`s. In particular, this allows the conversions system to handle the differing typing requirements based on whether the output type of the style function is interpolatable or non-interpolatable.
The X.Y.Z version portion was unreliable, as it pulled from the latest tag regardless of platform. Set version to 0.0.0 and retrieve only the hash, which allows us to drop the node/npm dependency.
This commit also gets rid of private `MGLOfflinePackDelegate` protocol.
`userInfo` dictionary in notification objects retain the `state` and
`progress` values for backwards compatibility. They can be removed in
later major release.
Replaced the style layer integration tests with unit tests. Test conversion of style values to property values and vice versa, not just round-tripping. Test the initial state and null-resetting of each null-resettable property. Test NSValue additions for style attribute enumerations. Test properties common to all style layer classes. Test MGLStyle’s source and layer collections.
Eviscerated implementations of unavailable style layer properties corresponding to style specification properties that were renamed. Implemented corresponding getters to prevent ivars from being autosynthesized for these unavailable properties.
Added a missing bridging header to the iOS test project.
This adds two new convenience initializers to MGLShapeSource:
-initWithIdentifier:features:options: takes an array of shape objects
that conform to MGLFeature, inserts them in a shape collection feature
and creates a source with that shape. -initWithIdentifier:shapes:options
does the same but with concrete MGLShape objects that get added to
a shape collection.
Throw an exception if an shape source is created with the features
initializer but is sent an array of features that contains something
that is not actually an object that conforms to the feature protocol.

* [ios, macos] Made MGLMapView.style property nullable
MGLMapView’s style property is now nullable (optional in Swift). The property is set to nil while the style loads and in the event that the style has failed to load.
* [ios, macos] Switch to delegate method
* [macos] Create MGLMapView programmatically for layer tests
When MGLMapView is created via a nib, -initWithCoder: is called, causing styleURL to be set to nil, in turn causing the default Streets style to be loaded, fooling MGLStyleLayerTests into thinking one-line has been loaded. Instead, create MGLMapView programmatically, passing the intended style URL into the initializer, preventing Streets from being loaded.
The screen origin is at the lower-left, so offsets and translations increase rightwards and upwards, in contrast to iOS and Web contexts, where the coordinate system increases rightwards and downwards. Duplicated style layer property declarations to reflect this difference.
* [ios, macos] Document requirement about adding sources and layers
Sources and layers added outside of mapView:didFinishLoadingStyle:
and mapViewDidFinishLoadingMap: are not guaranteed to appear
since the map may not be fully loaded and ready to accept new
sources and layers.
This also fixes a compiler warning in iosapp.
Reduced the likelihood that the developer might attempt to set textField to an NSTextField or UITextField, or textFont to an NSFont or UIFont, or textSize to a CGSize or NSSize, or circlePitchScale to a number (given iconScale).
Eliminated the separate NSValue+MGLStyleLayerAddition files, moving the categories into their respective style layer headers to be closer to the enumeration declarations.
Refined the types of MGLStyle’s sources and layers types so that Objective-C code can easily send messages intended for subclasses of MGLSource or MGLStyleLayer that are contained in one of these containers.
