Just to be clear, this isn’t preventing people from setting image widths to say
`5.0\linewidth', it just prevents them from being previewed at 5x the buffer text
width as that seems a bit ridiculous. Happy to reconsider the [0,2] preview
restriction, but I don’t think ridiculously large in-buffer images make much
sense.

All the best,
Timothy
