[Therion] Font size

I thought I'd experiment with font sizes, as the text in all my pdf files has always being rather small. As a first step I added the following 2 lines to a layout for an existing map. code metapost fonts_setup(6,8,10,14,20); The sizes selected above are, I think, the defaults used by Therion, and so I would expect the pdf documents produced to be identical to those without the above code. As it turns out the fonts produced with the above are significantly larger (although more closely matching the stated font sizes). So either something is wrong somewhere, or Therion is really using default font sizes much smaller than is stated in the Therion Book I can send two pdf examples if wanted. Bruce
