### ✨ New features

- [core] Implement stretchable icons ([#16030](https://github.com/mapbox/mapbox-gl-native/pull/16030))

[Stretchable icons](https://github.com/mapbox/mapbox-gl-js/issues/8917) allow defining certain areas of an icon that may be stretched, leaving the remaining areas of an icon at a fixed size.

- [core] Port line-sort-key and fill-sort-key ([#15839](https://github.com/mapbox/mapbox-gl-native/pull/15839))

The new feature allows to sort line and fill layer features. Similar to `symbol-sort-key`.
