All the fancy transitions and builds in the deck.js intro are handled
via CSS. So, the exporter will handle them easily.

If you look at the source for the intro, you will see that all the
builds and transitions are defined in home.css, and applied based on
slide id and/or class.

If you look at the documentation for ox-deck
@https://github.com/cybercode/org-slides, you will see that you can
specify per-slide classes via the HTML_CONTAINER_CLASS property on the
headline (and any headline can be build by setting the "slide" class
on the headline).

Taking a quick look @ the impress.js docs, i noticed that there is an
S9 template for impress.js
(http://slideshow-s9.github.io/slideshow-impress.js), and that
everything is specified w/ slide properties (x, y, z, scale and
rotate), so I would use headline PROPERTIES ( :IMPRESS_X, etc) to
define the slideshow.

Also note that it might be easier to inherit from  ox-s5 instead of
ox-deck as it is more generic (and add a wrapper around
`org-s5-headline') to process the additional properties.
