 *
 * Two additional properties will be set on the provided layer:
 *
 *  * `mapbox-source`: The `id` of the Mapbox Style document's source that the
 *    OpenLayers layer was created from. Usually `apply()` creates one
 *    OpenLayers layer per Mapbox Style source, unless the layer stack has
 *    layers from different sources in between.
 *  * `mapbox-layers`: The `id`s of the Mapbox Style document's layers that are
 *    included in the OpenLayers layer.
 *
 * This function also works in a web worker. In worker mode, the main thread needs
 * to listen to messages from the worker and respond with another message to make
 * sure that sprite image loading works:
 *
 * ```js
 *  worker.addEventListener('message', event => {
 *   if (event.data.action === 'loadImage') {
 *     const image = new Image();
 *     image.crossOrigin = 'anonymous';
 *     image.addEventListener('load', function() {

 *   }
 * });
 * ```
 *
 * @param {VectorLayer|VectorTileLayer} olLayer OpenLayers layer to
 * apply the style to. In addition to the style, the layer will get two
 * properties: `mapbox-source` will be the `id` of the `glStyle`'s source used
 * for the layer, and `mapbox-layers` will be an array of the `id`s of the
 * `glStyle`'s layers.
 * @param {string|Object} glStyle Mapbox Style object.
 * @param {string|Array<string>} sourceOrLayers `source` key or an array of layer `id`s
 * from the Mapbox Style object. When a `source` key is provided, all layers for
 * the specified source will be included in the style function. When layer `id`s
 * are provided, they must be from layers that use the same source.
 * @param {Array<number>} resolutions
 * Resolutions for mapping resolution to zoom level.
 * @param {Object} spriteData Sprite data from the url specified in
 * the Mapbox Style object's `sprite` property. Only required if a `sprite`
 * property is specified in the Mapbox Style object.
 * @param {string} spriteImageUrl Sprite image url for the sprite
 * specified in the Mapbox Style object's `sprite` property. Only required if a
 * `sprite` property is specified in the Mapbox Style object.
 * @param {function(Array<string>, string=):Array<string>} getFonts Function that
 * receives a font stack and the url template from the GL style's `metadata['ol:webfonts']`
 * property (if set) as arguments, and returns a (modified) font stack that
 * is available. Font names are the names used in the Mapbox Style object. If
 * not provided, the font stack will be used as-is. This function can also be
 * used for loading web fonts.
 * @param {function(VectorLayer|VectorTileLayer, string):HTMLImageElement|HTMLCanvasElement|string|undefined} [getImage=undefined]
 * Function that returns an image or a URL for an image name. If the result is an HTMLImageElement, it must already be
 * loaded. The layer can be used to call layer.changed() when the loading and processing of the image has finished.
 * This function can be used for icons not in the sprite or to override sprite icons.
 * @return {StyleFunction} Style function for use in
 * `ol.layer.Vector` or `ol.layer.VectorTile`.
