Adding footer at bottom of slide needs script after reveal initialization.
I need to put a footer slug at the bottom of slides. The org-re-reveal footer shows up at the end of the content of the slide, which is distracting for boring repetitive info like copyright and twitter handle.
There are techniques for adding a footer dynamically to either 'div.reveal' or '.slide-background' if the deck is being printed. This requires adding some script after initializing reveal. See https://github.com/hakimel/reveal.js/issues/806#issuecomment-222417787 Unfortunately the postamble is emitted before the script initialization.
Could the postamble be moved, or alternatively add a postscript chunk?
