[Therion] Scaling the entire output

The easiest way for me is to use PDF24 "Change PDF page size", which 
does exactly what I need. (It also has a few other things like "Edit 
PDF" which lets me add annotations for a magazine who wants them on an 
illustration for an article.)

I was mainly wondering if I had missed how scaling works, and whether 
there was already something in Therion's config options that made it 
actually scale the whole output. If there isn't, then there isn't, and I 
will make them a perfect PDF scaled to their needs. :)
