Comment 8 for bug 1853155

Ya, that was a concern. To avoid the scaling, I used a ---custom-size with a width reduced by the gutter size. Then the ghostscript call increases the width of all pages and offsets every other page's content using the postscript code described in the previous link. That author's scaling problem stemmed from the fact that the author had no control over the size of the incoming PDF, whereas I do because I'm using ebook-convert to generate it.
