/**
 * Checks if two Rectangles intersect.
 *
 * A Rectangle intersects another Rectangle if any part of its bounds is within the other Rectangle's bounds. As such, the two Rectangles are considered "solid". A Rectangle with no width or no height will never intersect another Rectangle.
 *
 * @function Phaser.Geom.Intersects.RectangleToRectangle
 * @since 3.0.0
 *
 * @param {Phaser.Geom.Rectangle} rectA - The first Rectangle to check for intersection.
 * @param {Phaser.Geom.Rectangle} rectB - The second Rectangle to check for intersection.
 *
 * @return {boolean} `true` if the two Rectangles intersect, otherwise `false`.
