Is it possible to render larger than my preview window? I have my window set to 800x800, which is pretty much the maximum height for my laptop and still be able to see and use the tools. Sometimes I'd like to work in 800x800 but render the image larger than that IE: 1000x1000....is it possible?

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
