mapbox-gl

⚠️ Breaking changes ⚠️

• Replace fill-extrude-height and fill-extrude-base properties of fill render type with a separate fill-extrusion type (with corresponding fill-extrusion-height and fill-extrusion-base properties), solving problems with render parity and runtime switching between flat and extruded fills. https://github.com/mapbox/mapbox-gl-style-spec/issues/554
• Change the units for extrusion height properties (fill-extrusion-height, fill-extrusion-base) from "magic numbers" to meters. #3509
• Remove mapboxgl.Control class and change the way custom controls should be implemented. #3497
• Remove mapboxgl.util functions: inherit, extendAll, debounce, coalesce, startsWith, supportsGeolocation. #3441 #3571
