     *
     * If `bounds` are specified, `zoomLevel` and `distance` parameters are ignored and `lookAt`
     * calculates best zoomLevel (and possibly target) to fit given bounds.
     *
     * Following table shows how relation between `bounds` and target.
     *
     * | `bounds`             | `target`    | actual `target`
     * | ------               | ------      | --------
     * | {@link @here/harp-geoutils#GeoBox}           | _defined_   | `params.target` is used
     * | {@link @here/harp-geoutils#GeoBox}           | `undefined` | `bounds.center` is used as new `target`
     * | {@link @here/harp-geoutils#GeoBoxExtentLike} | `undefined` | current `MapView.target` is used
     * | {@link @here/harp-geoutils#GeoBoxExtentLike} | _defined_   | `params.target` is used
     * | [[GeoCoordLike]][]   | `undefined` | new `target` is calculated as center of world box covering given points
     * | [[GeoCoordLike]][]   | _defined_   | `params.target` is used and zoomLevel is adjusted to view all given geo points
     *
     * In each case, `lookAt` finds minimum `zoomLevel` that covers given extents or geo points.
     *
     * With flat projection, if `bounds` represents points on both sides of anti-meridian, and
     * {@link MapViewOptions.tileWrappingEnabled} is used, `lookAt` will use this knowledge and find
     * minimal view that may cover "next" or "previous" world.
     *
     * With sphere projection if `bounds` represents points on both sides of globe, best effort
     * method is used to find best `target``.
     *
     * #### Examples
     *
     * ```typescript
     * mapView.lookAt({heading: 90})
     *     // look east retaining current `target`, `zoomLevel` and `tilt`
     *

 * quadtree).
 *
 * Within each [[level]], any particular tile is addressed with [[row]] and [[column]]. The number
 * of rows and columns in each level is 2 to the power of the level. This means: On level 0, only
 * one tile exists, [[columnsAtLevel]]() and [[rowsAtLevel]]() are both 1. On level 1, 4 tiles
 * exist, in 2 rows and 2 columns. On level 2 we have 16 tiles, in 4 rows and 4 columns. And so on.
 *
 * A tile key is usually created using [[fromRowColumnLevel]]() method.
 *
 * `TileKey` instances are immutable, all members return new instances of `TileKey` and do not
 * modify the original object.
 *
 * Utility functions like [[parent]](), [[changedLevelBy]](), and [[changedLevelTo]]() allow for
 * easy vertical navigation of the tree. The number of available rows and columns in the tile's
 * level is given with [[rowCount]]() and [[columnCount]]().
 *
 * Tile keys can be created from and converted into various alternative formats:
 *
 *  - [[toQuadKey]]() / [[fromQuadKey]]() - string representation 4-based
 *  - [[toHereTile]]() / [[fromHereTile]]() - string representation 10-based
 *  - [[mortonCode]]() / [[fromMortonCode]]() - number representation
