Re: Introducing Master of Ceremonies, a package for presentations

I've updated the no-margins branch.

I reproduced your issue by setting a fringe face background different
than my default face background.  MoC now sets fringe face background
to nil and restores it after done.  While I did also resize the
fringes to zero, unless I can handle the echo area fringes and restore
those, I cannot be more surgical at this time.

Tangentially, the branch also contains overlay persistence and
playback I just added, which can help displaying fancy org modern
excerpts.  I hope this doesn't confound our effort.

Let me know if this helps.
