Description Ken Sharp 2011-06-27 13:23:14 UTC 
Since some point after the adoption of ICC colour prfiles, if we set -dUseCIEColor for pdfwrite then we get a PDF file which includes a '0 g' at the end of each page.

This is caused by the showpage doing an erasepage by filling an empty path.

Because of the way that this is reflected in pdfwrite, we end up setting DeviceGray. We don't use it, but we do set it, and this can cause PDF/A validators to complain, because DeviceGray is only valid if we have set an OutputProfile.
