/**
 * @typedef {Object} Options
 * @property {string} url URL to the OGC Map Tileset endpoint.
 * @property {Object} [context] A lookup of values to use in the tile URL template.  The `{tileMatrix}`
 * (zoom level), `{tileRow}`, and `{tileCol}` variables in the URL will always be provided by the source.
 * @property {string} [mediaType] The content type for the tiles (e.g. "image/png").  If not provided,
 * the source will try to find a link with rel="item" that uses a supported image type.
 * @property {import("../proj.js").ProjectionLike} [projection] Projection. By default, the projection
 * will be derived from the `crs` of the `tileMatrixSet`.  You can override this by supplying
 * a projection to the constructor.
 * @property {import("./Source.js").AttributionLike} [attributions] Attributions.
 * @property {number} [cacheSize] Tile cache size. The default depends on the screen size. Will be ignored if too small.
 * @property {null|string} [crossOrigin] The `crossOrigin` attribute for loaded images.  Note that
 * you must provide a `crossOrigin` value if you want to access pixel data with the Canvas renderer.
 * See https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_enabled_image for more detail.
 * @property {boolean} [imageSmoothing=true] Deprecated.  Use the `interpolate` option instead.
 * @property {boolean} [interpolate=true] Use interpolated values when resampling.  By default,
 * linear interpolation is used when resampling.  Set to false to use the nearest neighbor instead.
 * @property {number} [reprojectionErrorThreshold=0.5] Maximum allowed reprojection error (in pixels).
 * Higher values can increase reprojection performance, but decrease precision.
 * @property {import("../Tile.js").LoadFunction} [tileLoadFunction] Optional function to load a tile given a URL. The default is
 * ```js
 * function(tile, src) {
 *   tile.getImage().src = src;
 * };
 * ```
 * @property {boolean} [wrapX=true] Whether to wrap the world horizontally.
 * @property {number} [transition] Duration of the opacity transition for rendering.
 * To disable the opacity transition, pass `transition: 0`.
