@generic {Phaser.Geom.Rectangle} O - [out,$return]

@param {number} x1 - The X coordinate of the first point.
@param {number} y1 - The Y coordinate of the first point.
@param {number} x2 - The X coordinate of the second point.
@param {number} y2 - The Y coordinate of the second point.
@param {Phaser.Geom.Rectangle} [out] - Optional Rectangle to adjust.

@return {Phaser.Geom.Rectangle} The adjusted `out` Rectangle, or a new Rectangle if none was provided.
