* [ios] Use map view frame to calculate annotation view reuse adjustments
The value for determining the visible viewport buffer and also the distance to move offscreen an annotation view outside of that buffer was based on the annotation view width and height. This changes that to use the map viewport width and height as constants and avoids a class of bugs where the annotation view would become detached from the tracking system when it did not have a size or was animating from a small to large size.
Pulled various translations from Transifex.
Although Transifex supports the stringsdict format, it doesn’t allow translators to customize the format. This change splits out a separate “level” key for the same format string and moves any prefixes and suffixes into the “level” and “count” keys. For now, each localization has been updated manually, but future updates will come from Transifex.
This reverses #3095. Rationale:
* We're now exposing source attributes as a public API. Making those attributes unavailable at certain times complicates that API.
* We're preparing to split RenderSource out of Source. Removing this removes a point of coupling between the two.
* [ios] added a scale bar
* [ios] update design
* [ios] show/hide scale bar
* [ios] Remove the need to localize 0
* [ios] Support for imperial units
* [ios] Round to nearest foot
* [ios] Make scale bar private
* [ios] Update design and clean up
* [ios] Rename and various optimizations
* [ios] RTL support
* [ios] added max scale and removed animations
* [ios] animate scale bar
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.
