`LayerManager` is now responsible for `RenderLayer` instances creation,
so that there is a single entry point for creating of objects, which
correspond to a certain layer type.
The `LayerType type` field is dropped from `Layer::Impl`.
* [ios, macos] Introduced more ergonomic expression concatenation syntax
* [ios, macos] Fixed mgl_join:
* [ios, macos] Simplified expression document headings
* [ios, macos] Documented mgl_join:
* [ios, macos] Convert length operator to length: for strings
Only works for literal strings.
* [ios, macos] Implemented type conversion using CAST()
* [ios, macos] Aftermarket let expressions
* [ios, macos] Refactored aftermarket expression functions
Refactored the installation of aftermarket expression functions to use macros. It is no longer necessary to handwrite the type encoding of a function. Also added aftermarket functions for interpolating and stepping.
* [ios, macos] Updated documentation, tests, demo apps
* [ios, macos] Added generic expression function
* [ios, macos] Add MGL_MATCH function placeholder.
* [ios, macos] Add MGL_SWITCH expression operator.
* [ios, macos] Add mgl_coalesce: as expression function.
* [ios, macos] Update style documentation.
* [ios, macos] Add conventional custom function support.
* [ios, macos] Updated example code
* [ios, macos] Add mgl_coalesce conventional custom function support.
* [ios, macos] Add aftermarket function to 'has' operator.
* [ios, macos] Add documentation for lookup and feature operators.
* [ios, macos] Documented simple lookup
* [ios, macos] Renamed, reversed has expression
Renamed mgl_hasProperty:properties: to mgl_does:have: for better readability and consistency with the conventional mgl_has: function. Documented both forms of mgl_has:.
* [ios, macos] Restored OEM conditionals where available
This is the preferred syntax for simple conditionals on iOS 9 and above, because you can inline the predicate instead of wrapping it in a constant value expression, which means you can write a conditional in a single format string.
* [ios, macos] Update style docs.

* [ios, macos] Import headers, not implementation files
* [core] Added accessors for various expression parameters
Added missing parameter accessors to various expression operator classes, as well as a method on InterpolatorBase and Step that enumerates the stops and their values.
* [ios, macos] Silenced warning in test of error condition
* [ios, macos] Made MGLSphericalPosition boxable
* [ios, macos] Implemented array enumeration during conversion
* [ios, macos] Temporarily ignore heatmap layer type
* [ios, macos] Migrated MGLSymbolStyleLayer.text to NSExpression
MGLSymbolStyleLayer.text is now of type NSExpression instead of MGLStyleValue, as a first step toward migrating the entire layer API from style values to expressions.
Implemented conversions from NSExpression to JSON arrays and vice versa. The most common NSExpression functions are now converted into style expressions, but not all of the most common style expression operators are supported yet.
* [ios, macos] Implemented string coercion
* [ios, macos] Color literals
* [ios, macos] Null constant expressions
* [ios, macos] Convert dictionary literals
* [ios, macos] Interpolation expressions
* [ios, macos] to-boolean, to-number, get from object
* [ios, macos] Variable expressions
Implemented custom expression functions for assigning and referring to variables within the context of an expression. Variables are assigned via a “context dictionary” and applied to an subexpression that is given as another argument to the same expression. Also implemented built-in variable expressions for zoom level and heatmap density.
* [ios, macos] Convert colors, offsets, padding in expressions to JSON objects
* [ios, macos] Expression-based style property getters
Implemented a conversion from mbgl::style::PropertyValues to Objective-C JSON objects, which are then converted to NSExpressions.
* [ios, macos] Consolidated property value–expression conversion in MGLStyleValueTransformer
* [ios, macos] Predicate and expression guide
Extracted documentation about predicates from a documentation comment in MGLVectorStyleLayer.h to a new jazzy guide. Added details about NSExpression support as well. Began updating the “For Style Authors” guide to reflect the transition from style values to expressions.
* [ios, macos] Updated style authoring guide
Updated the Information for Style Authors guide to discuss expressions instead of style functions. Included a table mapping style specification expression operators to NSExpression syntaxes.
* [ios, macos] Migrated codegen templates to expressions
* [ios, macos] Applied expression changes via codegen
Ran make darwin-style-code.
* [macos] Migrated macosapp to expressions
* [ios, macos] Updated style function guide
This guide needs to be thoroughly rewritten, but for now the example code has been migrated to expressions.
* [ios, macos] Eviscerated style function tests
* [ios, macos] Updated changelogs
* [ios] Migrated iosapp to expressions
* [ios, macos] Exposed JSON conversion methods publicly
* [ios, macos] Removed MGLStyleValue, MGLStyleFunction
* [ios, macos] new struct MGLTransition
* [ios] MGLTransition struct moved to MGLTypes.h
* [ios] MGLTransition implemented for style layer properties
* [ios, macos] added support for getting property transitions
* [ios, macos] updated to MGLDurationFromTimeInterval and MGLTimeIntervalFromDuration
* [ios, macos] added transition properties test
* [ios, macos] modified key strings imp
* [ios, macos] The impl for transition properties were changed to public methods
* [ios, macos] Changelog update
* [ios] Fixed layer space formatting
* [core] The name space was fixed for getters that returned TransitionOptions
* [ios, macos] Added rawLayer transition property tests
* [ios] Added a factory method for MGLTransition and transition-related methods to NSValue(MGLAdditions)
* [ios, macos] Copyedited changelog blurbs about transition properties
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.
