A behavior that transforms an object into a bounding box.
The parent stretches to become the bounding box of all children. I just added a new example that shows how to use this
I ran the example. It just forms a cross at the center of the screen, instead of scaling the box to surround the sprites.
I think the issue is that the children objects all need to have their hierarchy inheriting properties disabled, so that they dont translate/scale etc of the parent object.
Good catch, I updated the example to reflect that.
