Updated cups-filters to 1.11.1.

CHANGES IN V1.11.1

	- mupdftoraster: Lowered the priority (raised the cost value)
	  in the cupsfilters-mupdf.convs file so that in a full
	  cups-filters installation MuPDF is not prioritized.

CHANGES IN V1.11.0

	- pdftops: Added support for MuPDF as PDF renderer. MuPDF can
	  be selected by the "pdftops-renderer=mupdf" option.
	- rastertops: Removed unneeded page logging.
	- rastertops: Fixed DSC comments, some were only preceded by
	  a single '%' instead of a double "%%".
	- gstoraster, pdftops, foomatic-rip: Use -dNOMEDIAATTRS when
	  calling Ghostscript. This way Ghostscript does not try to
	  match media sizes with internal lists.
	- Build system: Allow building cups-filters without Poppler
	  (--disable-poppler in ./configure command line) This skips
	  the build of pdftoraster, bannertopdf, pdftoijs, and
	  pdftoopvp and the installation of these filters and their
	  auxiliary files. With this cups-filters can be easily
	  installed on mobile/appliance systems with MuPDF as the only
	  PDF interpreter.
	- mupdftoraster: Added filter to support MuPDF as PDF
	  interpreter. MuPDF is a lightweight PDF interpreter
	  especially interesting for mobile systems and
	  appliances. Thanks to Pranjal Bhor for contributing this as
	  part of his Google Summer of Code project.
	- gstoraster: Fix setting of width and height of the page in
	  pixels when there is no Resolution option in the PPD.
	- cups-browsed, implicitclass: Avoid the use of files for the
	  communication between cups-browsed and the load-balancing
	  backend implicitclass. Instead of in a file, cups-brwsed
	  stores the destination server name in an option (which CUPS
	  saves in printers.conf) which the implicitclass backend
	  reads via IPP. This not only makes it easier to run
	  cups-filters in a sandbox, but it is also better in terms of
	  system security.
	- cups-browsed: Allow configuring where the files produced by
	  cups-browsed will get stored. This makes it easier to run
	  cups-filters in a sandbox.
        - beh: Fixed printing multiple copies with beh (Ubuntu bug
          #1605514).
	- cups-browsed: Fixed several memory leaks, especially when
	  using IPP requests and DNS-SD TXT record look-ups. Thanks to
	  Ivo Straka for finding them with Valgrind and supplying
	  patches to fix them (Bug #1365, Bug #1368, Ubuntu bug
	  #1203276).
	- libcupsfilters: Added missing "#include <cups/ppd.h>" to
	  make sure that the package builds on all systems (Bug
	  #1366).
