Insert a block-level image. The @racket[_image-file] should be supplied as a filename only, with no
folder names. It is assumed that the image is located inside an @racket[images-folder] within the
same folder as the source document.

For web output, using @racket[figure-@2x] will produce an image hard-coded to display at half its
actual size, or the width of the text block, whichever is smaller.

@defproc[(image-link [image-file string?] [link-text xexpr?] ...) txexpr?]

Adds a hyperlink to @racket[_image-file], supplied as a filename only with no folder names. It is
assumed that the image is located inside an @racket[images-folder] within the same folder as the
source document.

@deftogether[(@defproc[(fn    [fn-id stringish?]) txexpr?]
              @defproc[(fndef [fn-id stringish?] [elements xexpr?] ...) txexpr?])]

As with hyperlinks, footnotes are specified reference-style. In the output, footnotes will be
numbered according to the order in which their identifiers are referenced in the source document.
