Is it possible to change crop size inside tween ?
As it was in Phaser 2: Phaser - Examples - Sprites - Horizontal Crop
cropRect = new Phaser.Rectangle(0, 0, 0, pic.height);
// Here we'll tween the crop rect, from a width of zero to full width, and back again
var tween = game.add.tween(cropRect).to( { width: pic.width }, 3000, Phaser.Easing.Bounce.Out, false, 0, 1000, true);
pic.crop(cropRect);
tween.start();
