Should we care about -dpreview combined with other backends though?  I
realize it's nonsensical to set it in combination with the null and
scm backends, but they also cause LilyPond to crash, so it might be
better either to add dummy output-preview-framework functions
(possibly with a warning message) or filter unsupported backends in
Paper_book::output ().
