After the introduction of colorless themes (#68) the PDF export currently breaks if you use that (the PDF looks all compacted). Now, I could fix this in presenterm-export so it doesn't look all compacted. However, the background color will be the default browser background color which is probably white and therefore your presentation will look terrible. This instead makes the code fail early so we don't even attempt to generate the PDF if you use that; you should pick a theme that uses specific background colors instead.
