removing and readding is a bit expensive. Are you scaling the content of a component? You should just set the scaleX,scaleY and reposition.

Now that I understand how children are added/removed i can take out some of my work arounds in other projects! The scaling works great now. New question: Is this the best way to scale? Is it expensive to remove and re-add all the components when I want to redraw? In this component I have graphics and text and it seems really fast. But what if I used more complex things like sprites or containers? Would removing all of them then re-adding them be the best way to redraw?
