Hi Alan, thank you for the report. I forgot to use the fontScale variable, although I calculate it correctly. I fixed some other minor problems with the pdf driver and the superscripts/subscript constant size issue should be fixed now. There are still some other problems, since e.g. example 24 segfaults. The pdf driver needs to be added to the test scripts.
