James R. Barlow 17ac9d7a9a Embed ICC profile in .ps (fixing Ghostscript 9.28 compatibility) 
Previously we included the
   filename, which required Postscript to run with file access enabled. For
   security, Ghostscript 9.28 enables ``-dSAFER`` and as such, no longer
   permits access to any file by default. This fix is necessary for
   compatibility with Ghostscript 9.28.

We use ASCII85 for a slightly more compact representation.

James R. Barlow 632dab2cc0 Replace Ghostscript DOCINFO and fix 9.25 metadata date regression 
We no longer use Ghostscript to manage PDF metadata, instead
omitting the DOCINFO segment from the pdfmark file we generate.

Instead all of the relevant metadata code has been migrated to pikepdf,
and we use that API. This should be more consistent and fixes the
Ghostscript version-depedent quirks.

Also removes our python-xmp-toolkit dependency, except for
testing.

James R. Barlow 96ba75eabd Ghostscript: fix issues in strict ASCII implementation 2018-09-16 15:41:54 -07:00
James R. Barlow 517b385fe5 Work around loss of Unicode DOCINFO in Ghostscript 9.24+ 
Ghostscript no longer supports UTF-16-BE-hex strings as a way of
supplying Unicode data in pdfmark so we have lost this functionality too:
http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=e997c6836d243ab37fe3a5f0d57974af95eb5eac

For users this means setting --title, --author, etc. will not work if gs
9.24 is installed, but if the file has existing metadata it might work.

For now we enforce police-state-strict ASCII, until there's time to
implement proper metadata editing. Relevant tests set to xfail.
