[Therion] Automatic scaling of itm xxtPDF output

[Martin Sluka]

Take care that softwares used for preparation of data for printing (RIP) may have problems with rasterisation of vector data - from there is limit for line width. More secure way is to rasterize pdf to bitmap with high resolution, let’s say 600 dpi, and send such file to magazine.
