flip images using CSS

Flipping of images in HTML output using the CSS.

Applies on top of the git's master.

I make it up as I go ;)

Seriously though, I have seen several server-side solutions and they use some
sort of patched up pdf2html or pdf2xml based on the Xpdf (and feed their output
into their own converters). Googling pdf2(whatever) also pretty much never
shows the poppler. calibre was the first thing I have ever seen (and at that in
its source code) using the poppler for PDF conversion. Conjecture at best, but
the best one I got. Overall the pdftohtml, even with -xml switch, is still
lagging in many areas behind other alternatives which do e.g. cropping support
and more detailed output, better suited for post-processing. And with the rise
of e-books, the post-processing is a must: paragraph detection at the very
least, scaling down images to save space, detecting/adding chapters, removing
page numbers, and so on.
