debian/rules: Demote texlive-lang-cjk from Recommends: to Suggests:
as it pulls in a large amount of unneeded packages (LP: #1449875).

* New upstream release
   - Ghostscript 9.16
   - "LockColorants" command line option for tiffsep and psdcmyk
     devices. Specifying -dLockColorants will restrict those devices to
     only the colorants list on the command line (thus: -c "<<
     /SeparationColorNames [ /Cyan /Magenta /Yellow /Black /Violet
     /Orange] /SeparationOrder [ /Cyan /Magenta /Yellow /Black /Violet
     /Orange]>> setpagedevice"), rather than allowing the devices to
     add new colorants as encountered in the input. This is, obviously,
     preferable for real printers, where only a certain of inks will be
     available.
   - Improved high level devices handling of Forms. Whilst High level
     devices (eg pdfwrite) already checked Forms to see if they are
     duplicates, and if so use the initial definition. However, this
     does not improve performance, since the Form PaintProc still needs
     to be executed for each instance of the Form, and the matching
     algorithm could, in very odd circumstances, be defeated. The new
     implementation benefits both causes, meaning the second and
     subsequent invocation of the form need not re-run the PaintProc,
     and removes the heurisic aspect of the reuse detection.
   - New URW+ fonts in which the families NimbusMono, NimbusRoman and
     NimbusSans have been augmented with production quality Greek and
     Cyrillic glyphs. These correspond to our substitutes for the PDF
     base 14 fonts.
   - Plus the usual round of bug fixes, compatibility changes, and
     incremental improvements.
* 020150413_3e71154_pdfwrite_optimise_pdf_foget_resource_with_charproc_resources.patch:
  Removed, included upstream.
* 2003_support_multiarch.patch: Refreshed with quilt.
* debian/rules: Added "zlib_h=" to "make" command line to work around
  bug in build system.
* debian/symbols.common: Updated for new upstream source. Applied patch
  which dpkg-gensymbols generated for debian/libgs9.symbols to this file.

debian/patches/020150724_0c0b085_sanity_check_for_memory_allocation.patch:
Added a sanity check for memory allocation, to avoid an integer overflow
(Upstream bug #696070, CVE 2015-3228).

* debian/patches/1003_gdevcups-fix-cupsrasteropen-pwg-raster.patch:
  Removed, not needed any more.
* debian/patches/020150523_d73a342_gdevcups_support_color_spaces_18_19_20.patch:
  "cups"/"pwgraster" output devices: Added support for color spaces
  18 (SGray), 19 (SRGB), and 20 (Adobe RGB).

020150413_3e71154_pdfwrite_optimise_pdf_foget_resource_with_charproc_resources.patch:
Fixed a long delay caused when Ghostscript converts PostScript files to PDF
where the PostScript comes from evince when printing a displayed DjVu file
(LP: #525161, Upstream bug #695778).

* New upstream release
   - Ghostscript 9.15
   - Ghostscript now supports the PDF security handler revision 6.
   - The pdfwrite and ps2write (and related) devices can now be forced to
     "flatten" glyphs into "basic" marking operations (rather than writing
     fonts to the output), by giving the -dNoOutputFonts command line option
     (defaults to "false")
   - PostScript programs can now use get_params or get_param to determine if
     a page contains color markings by reading the pageneutralcolor state
     from the device (so whether the page is "color" or "mono").
   - Note that this is only accurate when in clist mode, so -dMaxBitmap=0 and
     -dGrayDetection=true should both be used.
   - The pdfwrite device now supports Link annotations with GoTo and GoToR
     actions
   - The pdfwrite device now supports BMC/BDC/EMC pdfmarks
   - Regarding the new color management for the pdfwrite device introduced in
     the previous release, the proscription on using the new color management
     when producing PDF/A-1 compliant files is now lifted.
   - To reiterate, also, with the new color management implementation, using
     the UseCIEColor option is strongly discouraged.
   - For further information on the new pdfwrite color management, see: Color
     Conversion and Management
   - Plus the usual round of bug fixes, compatibility changes, and
     incremental improvements.

debian/patches/1003_gdevcups-fix-cupsrasteropen-pwg-raster.patch:
The CUPS Raster output device generated incorrect PWG Raster output
because it called cupsRasterOpen() without the required
CUPS_RASTER_WRITE_PWG mode setting. Due to the output never being
tested with an IPP Everywhere printer but only with software which
also accepts CUPS Raster, the bug did not get discovered until testing
the output against the mime type recognition of CUPS where it failed.
