/**
 * Applies a style function to an `ol/layer/VectorTile` or `ol/layer/Vector`
 * with an `ol/source/VectorTile` or an `ol/source/Vector`. If the layer does not have a source
 * yet, it will be created and populated from the information in the `glStyle` (unless `updateSource` is
 * set to `false`).
 *
 * **Example:**
 * ```js
 * import {applyStyle} from 'ol-mapbox-style';
 * import {VectorTile} from 'ol/layer.js';
 *
 * const layer = new VectorTile({declutter: true});
 * applyStyle(layer, 'https://api.maptiler.com/maps/basic/style.json?key=YOUR_OPENMAPTILES_TOKEN');
 * ```
 *
 * The style function will render all layers from the `glStyle` object that use the source
 * of the first layer, the specified `source`, or a subset of layers from the same source. The
 * source needs to be a `"type": "vector"` or `"type": "geojson"` source.
 *
 * Two additional properties will be set on the provided layer:
 *
 *  * `mapbox-source`: The `id` of the Mapbox/MapLibre Style document's source that the
 *    OpenLayers layer was created from. Usually `apply()` creates one
 *    OpenLayers layer per Mapbox/MapLibre Style source, unless the layer stack has
 *    layers from different sources in between.
 *  * `mapbox-layers`: The `id`s of the Mapbox/MapLibre Style document's layers that are
 *    included in the OpenLayers layer.
 *
 * @param {VectorTileLayer|VectorLayer} layer OpenLayers layer. When the layer has a source configured,
 * it will be modified to use the configuration from the glStyle's `source`. Options specified on the
 * layer's source will override those from the glStyle's `source`, except for `url` and
 * `tileUrlFunction`. When the source projection is the default (`EPSG:3857`), the `tileGrid` will
 * also be overridden. If you'd rather not have ol-mapbox-style modify the source, configure `applyStyle()`
 * with the `updateSource: false` option.
 * @param {string|Object} glStyle Mapbox/MapLibre Style object.
 * @param {string|Array<string>|Options&ApplyStyleOptions} [sourceOrLayersOrOptions] Options or
 * `source` key or an array of layer `id`s from the Mapbox/MapLibre 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. When not provided or a falsey
 * value, all layers using the same source as the first layer matching the provided `layer` type will be rendered.
 * @param {Options&ApplyStyleOptions|string} [optionsOrPath] **Deprecated**. Options. Alternatively the path of the style file
 * (only required when a relative path is used for the `"sprite"` property of the style).
 * @param {Array<number>} [resolutions] **Deprecated**. Resolutions for mapping resolution to zoom level.
 * Only needed when working with non-standard tile grids or projections, can also be supplied with
 * options.
 * @return {Promise} Promise which will be resolved when the style can be used
 * for rendering.

 * as style url, layers will be added to the map when the Mapbox/MapLibre Style document
 * is loaded and parsed.
