* Gets the tiles in the given rectangular area (in world coordinates) of the layer.

* @function Phaser.Tilemaps.Components.GetTilesWithinWorldXY
* @since 3.0.0
*
* @param {number} worldX - The world x coordinate for the top-left of the area.
* @param {number} worldY - The world y coordinate for the top-left of the area.
* @param {number} width - The width of the area.
* @param {number} height - The height of the area.
* @param {object} [filteringOptions] - Optional filters to apply when getting the tiles.
* @param {boolean} [filteringOptions.isNotEmpty=false] - If true, only return tiles that don't have -1 for an index.
* @param {boolean} [filteringOptions.isColliding=false] - If true, only return tiles that collide on at least one side.
* @param {boolean} [filteringOptions.hasInterestingFace=false] - If true, only return tiles that have at least one interesting face.
* @param {Phaser.Cameras.Scene2D.Camera} [camera=main camera] - The Camera to use when factoring in which tiles to return.
* @param {Phaser.Tilemaps.LayerData} layer - The Tilemap Layer to act upon.
