dataxvalue does not work with variables any more
Meanwhile we realised that it is not the embedded fonts that are increasing the size of the .pdf files. Instead (due to the new concept of layers?) the generation of the post script code produces much overhead. Would be great if there was a way to reduce this....
Wrong handling of non-existent data values ('*')
exit status code =0 in spite of ghostscript error
make embedding of fonts in PDF optional
