cups-filters: Update to 1.28.7

- Update cups-filters from 1.27.4 to 1.28.7
- Changelog
	CHANGES IN V1.28.7
		- driverless: Removed the support quality check from Pull
		  request #235 as it takes significant time for each printer
		  being listed, making cups-driverd (`lpinfo -m`) timing out
		  when there are many printers (OpenPrinting CUPS issue #65).
		- libcupsfilters: In the PPD generator give priority to Apple
		  Raster against PDF (Issue #331).
		- libcupsfilters: Added NULL check when removing ".Borderless"
		  suffixes from page size names (Issue #314, Pull request
		  #328).
		- libcupsfilters: In the cupsRasterParseIPPOptions() map the
		  color spaces the same way as in the PPD generator (Issue
		  #326, Pull request #327).
		- libcupsfilters: Fixed addition of grayscale mode in
		  generated PPD files, to avoid duplicate entries
		  (OpenPrinting CUPS issue #59).
	CHANGES IN V1.28.6
		- libcupsfilters: In generated PPDs add a grayscale mode if
		  there are only color printing modes (from OpenPrinting
		  CUPS).
		- libcupsfilters: In generated PPDs add an "OutputBin" option
		  also if it has only one choice (OpenPrinting CUPS pull
		  request #18).
		- libcupsfilters: Generated PPDs could have an "Unknown"
		  default InputSlot (OpenPrinting CUPS issue #44).
		- cups-browsed: Removed unneeded IPP attribute additions
		  preventing the created local queues from preserving a
		  location or description the user assigns to them (Issue
		  #323).
		- cups-browsed: Removed all calls of the resolve_uri() function
		  of libcupsfilters, as these are not actually needed and in case
		  the supplied DNS-SD-based URI is not resolvable, the function
		  gets stuck for ~5 seconds.
		- cups-browsed: Fixed several memory leaks, mainly from the
		  code to merge printer IPP attributes for clusters (Pull
		  request #322).
		- cups-browsed: Silenced compiler warning.
		- foomatic-rip: Fix infinite loop and input from file on raw
		  printing (Pull request #318).
		- foomatic-rip: Remove temporary file created during pdf-to-ps
		  conversion (Pull request #313).
	CHANGES IN V1.28.5
		- cups-browsed: UUID from IPP response was used after its
		  pointer was freed by ippDelete() (Pull request #311).
	CHANGES IN V1.28.4
		- driverless: Avoid duplicate PPD list entries from the same
	          device via UUID
		- driverless: Reduce ippfind calls by "driverless" and
		  "driverless-fax"called by CUPS. Let "driverless list" list
		  both print and fax PPDs and "driverless-fax list" do
		  nothing.
		- driverless: Avoid duplicate listings in printer discovery,
		  by "driverless-fax" not listing any URI as "driverless"
		  lists them all already.
		- driverless: Vastly improve performance by doing only one
		  ippfind call instead of two (IPP, IPPS) as ippfind accepts
		  more than one reg type on the command line.
		- Sample PPDs: Corrected manufacturer name in
		  Fuji_Xerox-DocuPrint_CM305_df-PDF.ppd.
	CHANGES IN V1.28.3
		- libcupsfilters, cups-browsed: Fixed inconsistency between
		  resolvers for DNS-SD-based URIs, resolve_uri() and
		  ippfind_based_uri_converter(). Now both return a freeable
		  string.
		- libcupsfilters: Fix uninitialized buffer and parsing ippfind
		  output in ippfind_based_uri_converter() function (Issue
		  #308, Pull request #309).
	CHANGES IN V1.28.2
		- driverless: Free allocated memory, use MAX_OUTPUT_LEN (Pull
		  request #304).
		- driverless: Make the two ippfind tasks(for IPP
		  and IPPS) run in parallel (Pull request #302, #305, #306).
		- braille: Support new liblouis tables not containing a
		  display name (Pull request #303)
		- Build system: Let ./configure not error out when there is
		  more than one DejaVuSans.ttf test font candidate (Issue
		  #300).
		- cups-browsed: Crash when a remote printer set as default
		  gets removed, due to missing variable in printf() call
		  (Issue #299).
		- libcupsfilters: Removed all signal handling and global
		  variables from get_printer_attributes() and
		  ippfind_based_uri_converter().  This is overkill for these
		  quick operations and causes problems when shutting down
		  cups-browsed (Issue #298).
	CHANGES IN V1.28.1
		- COPYING: Fixed several typos
		- libcupsfilters: Fixed typo in log message of
		  get_printer_attributes functions.
		- cups-browsed: Fixed typos in configuration file and man page
		- libcupsfilters: Let the PPD generator not suffix page size
		  names with ".Borderless" if all page sizes would get this
		  suffix, for example for printers which generally print
		  borderless.
		- libcupsfilters: Added "faxPrefix" option for generated IPP
		  Fax Out PPDs, so that this option also appears in print
		  dialogs.
		- driverless: List addresses for local services correctly when
		  using "--std-ipp-uris" (with "localhost" hostname).
		- driverless: Make calls of the ippfind utility somewhat faster,
		  setting the timeout of ippfind to automatic.
		- libcupsfilters: Resolve DNS-SD-based URIs for local services
		  correctly (using hostname "localhost").
		- libcupsfilters: In get_printer_attributes() functions do not
		  try to convert URIs which are not DNS-SD-based (Issue #294).
		- libcupsfilters: In get_printer_attributes() functions also
		  support URIs with "dnssd://..." scheme.
		- libcupsfilters: Moved signal handling back into main
		  function of the get_printer_attributes() variants, it got
		  moved out accidentally.
		- driverless: For generating a PPD, independent whether via
		  "driverless URI" or "driverless cat URI", always allow CUPS
		  driver URIs (prefixed with "driverless: " or
		  "driverless-fax:") and pure IPP URIs.
		- driverless: Accept clean IPP URIs also for 'driverless cat
		  ...' (Issue #295, Pull request #296).
		- driverless-fax: Do not use fixed path for call of driverless
		  itself (Pull request #293).
	CHANGES IN V1.28.0
		- driverless, driverless-fax, libcupsfilters: Added IPP Fax
		  Out support. Now printer setup tools list an additional fax
		  "driver".  A fax queue is created by selecting this
		  driver. Jobs have to be sent with "-o phone=12345" to supply
		  the destination phone number (Pull request #280).
		- libfontembed: Silenced warning with gcc 10.x (Pull request
		  #287).
		- cups-browsed: Added ./configure options
		  --enable-saving-created-queues and
		  --with-remote-cups-local-queue-naming (Pull request: #253,
		  #285).
		- cups-browsed: Fixed several memory leaks, mainly from the
		  code to merge printer IPP attributes for clusters (Pull
		  request #281, #283).
		- driverless: Added "--std-ipp-uris" command line option to
		  show listed URIs in standard hostname-based form (not the
		  CUPS DNS-SD-service-name-based form. Only for manual call of
		  the utility, for debugging purposes (Pull request #277).
		- libfontembed: Removed assert() calls which cause crashes
		  when unsupported emoji fonts are installed (Issue #254, Pull
		  request #276).
		- driverless: Added support for IPPS (use "ipps://..." URIs if
		  possible, Issue #251, Pull request #270, #273).
		- gstoraster, gstopdf: When converting PostScript to PDF use
		  the "pdfwrite" output device with "-dPDFSETTINGS=/default"
		  instead of with "-dPDFSETTINGS=/printer". This reproduces
		  bitmaps in the PostScript file with their original image
		  quality (Issue #272).
		- cups-browsed: Limit log file size and add backup file for
		  previous log entries. Introduced the configuration option
		  DebugLogFileSize in cups-browsed.conf to set the actual
		  limit in kilobytes or 0 to get the old behavior of an
		  unlimited size for the log file (Issue #260, Pull request
		  #267).
		- gstoraster, gstopdf: Do not apply margins when output format
		  is PDF, as then we convert an incoming PostScript file to
		  PDF (pre-pdftopdf) and do not prepare the pages for the
		  printer (post-pdftopdf, Issue #250).
		- cups-browsed: Do not write any log messages directly to
		  stderr, there were some concerning timeouts on queue
		  creation (Issue #260).
		- Build system: Fix cross-compilation without DejaVu test font
		  in configure.ac (Issue #262, Pull request #263).
		- libcupsfilters: Respect the fact that PPD keywords
		  are case-sensitive when adding "*cupsManualCopies: True" in
		  PPD file (Issue #242).
		- libcupsfilters: Older versions of libcups (< 2.3.1)
		  had the enum name for fold-accordion finishings mistyped.
		  Added a workaround.
		- cups-browsed: Remove left-over local queues from the
		  previous session more quickly when CUPS legacy browsing is
		  turned on.
		- cups-browsed: Left-over local queues from the previous
		  session for which the corresponding remote printer did not
		  appear again did not get removed as they were considered
		  externally overwritten.
		- gstoraster, gstopdf: Add option "-dDoNumCopies" to
		  Ghostscript command line if we are outputting PDF (called
		  via gstopdf wrapper) and the number of copies supplied to
		  CUPS is 1 (4th command line argument). In this case we
		  convert incoming PostScript to PDF and need to respect
		  embedded PostScript commands to implement the number of
		  copies (Issue #255, CUPS Issue #5796, OpenSUSE bug
		  #1173345).
		- imagetoraster: Potential null dereference fix (when no valid
		  PPD is supplied, Pull request #256).
		- cups-browsed: Call cupsGetNamedDest() only if
		  "OnlyUnsupportedByCUPS No"
		- Sample PPDs: Corrected ColorModel default for Generic PWG
		  Raster PPD to Color (Pull request #247).
		- cups-browsed: Mark the temp queue as cups-browsed-generated
	          during setting printer-is-shared (Pull request #246).
		- cups-browsed: Remove mentions of README and AUTHORS files in
	          the man page (Pull request #244).
		- pclmtoraster: Added new filter to extract Raster data from
		  raster-only PDF files, here for the special case of PCLm
		  files (Pull request #243, #257).
		- Sample PPDs: In Generic-PDF_Printer-PDF.ppd add option to
		  switch between color and grayscale printing (Pull request
		  #237).
	CHANGES IN V1.27.5
		- cups-browsed: Do not remove the created local queues on
		  shutdown, to avoid their re-creation on restart, so that
		  desktops get no cluttered with notifications of new queues
		  being created. One can return to the old behavior via
		  "KeepGeneratedQueuesOnShutdown No" in cups-browsed.conf
		  (Ubuntu bug #1869981, #1878241).
		- cups-browsed: Do not accept DNS-SD broadcasts of IPPS type
		  of "remote" CUPS queues of another CUPS instance on the
		  local machine. This way we get a local queue pointing to
		  such a printer only in unencrypted version (IPP). For some
		  reason printing from one CUPS server to another on the same
		  machine works only unencrypted.
		- foomatic-rip: Map two-sided-short-edge to DuplexTumble (Pull
	          request #236)
		- Build system: In configure.ac use AS_IF instead of
	          AC_CHECK_FILE for font check (Issue #239, Pull request #240)
		- cups-browsed: Cleaned up code for determining to which CUPS
		  server (host/port/domain socket) to connect, so that
		  connection via DomainSocket cups-browsed.conf directive,
		  CUPS_SERVER and IPP_PORT environment variables and all
		  defaults and methods of libcups, including CUPS' client.conf
		  work.
		- gstoraster, rastertopdf: Do not pass NULL to fprintf() (Pull
	          request #230).
		- libcupsfilters: Silence compiler warning (Pull request #229).
- rootfile updated
