Similarly to the previous commit, introduce `-[MGLStyleLayer initWithPendingLayer:]`, allowing the base class to track the owned `_pendingSource` pointer and implement `-addToMapView:` and `-removeFromMapView:` without any casts.
Fixes an issue where `-[MGLStyle layerFromMBGLLayer:]` would wind up creating layers whose `_rawLayer` and `_pendingLayer` held different values.
Invalid coordinates no longer cause an exception to be raised immediately when used in conversion methods and model objects. Instead, the appropriate invalid values are used, consistent with MapKit. Exceptions are still raised when invalid model objects are used with the map.
Replaced std::map::operator[] usage with std::map::at(). Backed up an assertion on iOS with a guard when -annotationTagsInRect: returns the tag of a nonexistent annotation, for consistency with macOS. Removed an unnecessary and risky subscript into _annotationContextsByAnnotationTag in -positioningRectForCalloutForAnnotationWithTag: on iOS.
* [ios, macos] Rename Data-driven styling guide
This turns the Data-driven styling guide into a guide for working with
style functions. This helps clarify that not all style functions are
DDS specific but keeps the discussion of this related functionality in
the same guide.
This silences a compatibility warning that was introduced in a previous
refactor that changed the return type of the callout view for
annotation delegate method. This also adds checks to ensure that the
callout view provided by the delegate to the map view is of the correct
type and conforms to the correct protocol.
Cursorily copy-edited the data-driven styling guide, removing a stray class reference, replacing a redundant h1, and making stops examples platform-agnostic and less redundant.
Fixed an issue in the style authors guide where style function tables appeared under each style layer type table.
`- (nullable UIView <MGLCalloutView> *)mapView:(MGLMapView *)mapView
calloutViewForAnnotation:(id <MGLAnnotation>)annotation;` bridges
with a `UIView?` return type in Swift. This changes replaces the
`UIView` type in the method signature so that, when bridged to Swift,
the returned object is defined as `MGLCalloutView?`.
* [ios, macos] Corrected map load error descriptions
Ensured the uniqueness of localizable string IDs. Ran make genstrings to add the -[MGLMapViewDelegate mapViewDidFailToLoad:withError:] error description strings to the base localization.
* [ios, macos] Moved failure error changelog entry to new release
