Rewrite printout rendering
- The current page is always centred when rendering in a GUI, with the turned pages moving from the sides. - Pages are no longer evenly distributed from the centre - they follow an exponential decay curve, so ones further out are closer together (a bit like an open book). - Render pages and books in item frames/in-hand (rather than just single pages). This currently does some very dirty things with z values in order to prevent z-fighting. It would be nice to avoid that, though turning off writing to the z buffer causes issues with the bounding box.
