As I said earlier, that CSS is pathetic and I wouldn't use it if I were you. It requires some JavaScript, which I haven't bothered to write, to predict the different width settings and to activate that CSS written above when, and only when, the setting is "Maximum". Hence, why I think it's silly. Truly a mallet to squash a pea scenario. Scratch that, a powered, mechanical mallet to squash a boiled pea.

The alternative I came up with in my previous post was to use JavaScript to create a scroll bar for zooming in and out of the preview. It wouldn't be that difficult to write, but releasing it now, while Darwin is in flux, would be counter productive.
