/**
* Sets the tiles in the given rectangular area (in tile coordinates) of the layer with the
* specified index. Tiles will be set to collide if the given index is a colliding index.
* Collision information in the region will be recalculated.
* Checks if the given tile coordinate is within the isometric layer bounds, or not.
*
* @function Phaser.Tilemaps.Components.CheckIsoBounds
* @private
* @since 3.50.iso
* @since 3.50.0
*
* @param {integer} tileX - The x coordinate, in tiles, not pixels.
* @param {integer} tileY - The y coordinate, in tiles, not pixels.
* @param {Phaser.Tilemaps.LayerData} layer - The Tilemap Layer to check against.
* @param {Phaser.Cameras.Scene2D.Camera} [camera] - The Camera to run the cull check against.
*
* @return {boolean} Returns `true` if the coordinates are within the iso bounds.
