Surely nothing is rendered for free. All rendering requires some rendering resources. Cheap and expensive, yes, but not Free. I suppose things which are not rendered on screen, eg AI or I/O script processing could be said to be free to render ... but they use other resources instead. --Beeswax 18:04, 14 Apr 2008 (PDT)

There's an example right there on the page. --TomEdwards 04:32, 15 Apr 2008 (PDT)
