http://gdal.org/ogr/drv_pdf.html lists the subset of the OGR Feature Style 
spec that is currently implemented by the PDF driver.

I believe that you should be able to workaround the lack of support of pre-
defined pens, by defining a pattern ('p' parameter) that should be supported.

I don't actively work on it anymore for now. Contributions under the form of 
patches ( hint: edit GDALPDFWriter::WriteOGRFeature() in  
frmts/pdf/pdfcreatecopy.cpp ) kindly welcome, or if you can identify a 
reasonable extra subset of the OGR FeatureStyle spec that would be interesting 
to add, you can create a ticket. At first sight, dx and dy for labels and/or 
symbols should be reasonably easy to implement.
