/**
* [description]
* Takes an array of Game Objects, or any objects that have public `scaleX` and `scaleY` properties,
* and then adds the given value to each of them.
*
* The optional `stepX` and `stepY` properties are applied incrementally, multiplied by each item in the array.
*
* To use this with a Group: `ScaleXY(group.getChildren(), scaleX, scaleY, stepX, stepY)`
*
* @function Phaser.Actions.ScaleXY
* @since 3.0.0
*
* @param {array} items - An array of Game Objects. The contents of this array are updated by this Action.
* @param {number} x - [description]
* @param {number} y - [description]
* @param {array|Phaser.GameObjects.GameObject[]} items - The array of items to be updated by this action.
* @param {number} scaleX - The amount to be added to the `scaleX` property.
* @param {number} [scaleY] - The amount to be added to the `scaleY` property. If `undefined` or `null` it uses the `scaleX` value.
* @param {number} [stepX=0] - This is added to the `scaleX` amount, multiplied by the iteration counter.
* @param {number} [stepY=0] - This is added to the `y` amount, multiplied by the iteration counter.
* @param {integer} [index=0] - An optional offset to start searching from within the items array.
* @param {integer} [direction=1] - The direction to iterate through the array. 1 is from beginning to end, -1 from end to beginning.
*
* @return {array} The array of Game Objects that was passed to this Action.
* @return {array} The array of objects that were passed to this Action.
