const actor = new ex.Actor({
    pos: ex.vec(100, 100),
    width: 100,
    height: 100
    color: ex.Color.Red
});

// Scale up the actor to twice the size, at .1 scale factor per second
actor.actions.scaleTo(ex.vec(2, 2), ex.vec(.1, .1));

```

    scale: ex.vec(2, 2)
    color: ex.Color.Red
});

// Scale the actor relative to it's current scale down to 1, at .1 scale factor per second
actor.actions.scaleBy(ex.vec(-1, -1), .1);
