## Detailed Description

Animator types are different from normal Animation types. When using an Animator, the animation can be run in the render thread and the property value will jump to the end when the animation is complete.

The value of Item::scale is updated after the animation has finished.

The following snippet shows how to use a ScaleAnimator together with a Rectangle item.

    Rectangle {
        id: scalingBox
        width: 50
        height: 50
        color: "lightsteelblue"
        ScaleAnimator {
            target: scalingBox;
            from: 0.5;
            to: 1;
            duration: 1000
            running: true
        }
    }

It is also possible to use the `on` keyword to tie the ScaleAnimator directly to an Item instance.

    Rectangle {
        width: 50
        height: 50
        color: "lightsteelblue"
        ScaleAnimator on scale {
            from: 0.5;
            to: 1;
            duration: 1000
        }
    }
