pandoc and revealjs r-fit-text and r-stretch?

[Joseph Reagle <joseph.2011-T1oY19WcHSwdnm+yROfE0A@public.gmane.org>]

I'd love to use revealjs's `r-fit-text` and `r-stretch` [1] in the new year, but they don't work with decks generated by pandoc.

`r-fit-text` doesn't work because pandoc applies the class to both the heading and the section, and so the element gets a double dose of movement [2].

And an `img.r-stretch` must be a child of the section, and pandoc typically puts img in another element (e.g., `p`).

Does anyone have any hacks for using these? Or, if this pandoc generated structure isn't likely to change, perhaps we should put a request in to Hakim to accommodate the pandoc structure?
