[hackers] [sent] [PATCH] Draw a progress bar on non-image slides

From: David Phillips <david_AT_sighup.nz>

Similar to the slide numbers patch, it may be useful for an audience
to know how much more of a presentation they have to endure. A naïve
approach to this is to introduce a progress bar to the bottom of the
slides which indicate the presenter's progress based on slide count.

This progress bar is not drawn on image slides, since it may clutter
and/or interfere with the figure on the slide.
