Class Bounds

Extends Point.
Represents a Rectangular area with x,y coordinates as well as width, and height.
Defined in: Bounds.js.

// Creates a new Bounds object using standard JSON.
var myBounds = Bounds({x: 10, y: 10, w: 100, h: 100});

Alerts true
alert(myBounds.contains(Bounds({x: 15, y: 15})));

Alerts true
alert(myBounds.contains({x: 20, y: 20, w: 20, h: 20}));

Alerts false
alert(myBounds.contains({x: 20, y: 20, w: 100, h: 100}));
This example alerts false, because when width and height are supplied, the
given bounds must be completely within the 'myBounds' area.

// Using a Bounds object.
var myBounds = Bounds({x: 10, y: 10, w: 100, h: 100});
// alerts 10
alert(myBounds.x);
// alerts 200
alerts(myBounds.w * myBounds.h);
