 * callback as the first and only parameter.
 * @param {object} [context] - The context under which the callback should be run.
 * @param {integer} [tileX=0] - [description]
 * @param {integer} [tileY=0] - [description]
 * @param {integer} [width=max width based on tileX] - [description]
 * @param {integer} [height=max height based on tileY] - [description]
 * @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 {LayerData} layer - [description]
