Title:
  PWG Raster printing on IPP Everywhere printers not working correctly

Bug description:
  Printers conforming to the new IPP Everywhere standard (of the
  Printing Working Group, PWG, http://www.pwg.org/) are starting to come
  onto the market. These printers are capable to inform the clients
  computers about all their capabilities (paper sizes, resolutions,
  finishers, ...) via IPP and understand known standard page description
  languages (always PWG Raster, but can also understand PostScript, PDF,
  JPEG, and/or PCL). So no drivers for these printers are needed. With
  CUPS, cups-filters, and one of Ghostscript, Poppler, or MuPDF they are
  fully supported.

  Yakkety is intended to support them, but getting my hands on an IPP
  Everywhere printer (which takes PWG Raster as inpout format) I have
  found some issues:

  - CUPS selects a filter chain using MuPDF but MuPDF is not installed
  by default.

  - In contrary to CUPS Raster, PWG Raster contains a full page bitmap
  of the page, including the unprintable margins. Margins in the header
  are set to zero.

  - Filter chains could send CUPS Raster instead of PWG Raster.

  - Printed pages are not logged in /var/log/cups/page_log.

  All these issued are fixed in cups-filters 1.11.5 and in a patch to
  Ghostscript (already upstream).

  This bug report is for an SRU for Yakkety to fix the issues also
  there.

  [Impact]

  With "CreateIPPPrinterQueues Yes" set in /etc/cups/cups-browsed.conf
  IPP Everywhere printers are discovered in the network and
  automatically set up but they only print if mutool (package mupdf-
  tools) is installed. This leaves users with non-working print queues.

  [Testcase]

  Set "CreateIPPPrinterQueues Yes" in /etc/cups/cups-browsed.conf and
  restart cups-browsed. If an IPP Everywhere printer is in the network,
  it will be detected but you cannot print on the auto-generated queue.
  After installing the mupdf-tools package printing works.

  With the fixed cups-filters and Ghostscript installed mupdf-tools is
  not needed. Jobs get filtered via Ghostscript and printing on the IPP
  Everywhere printer works.

  [Regression Potential]

  Small, as changes in the filter chain only happen if PWG Raster is
  involved and this happens only with IPP Everywhere printers. Only the
  output of PWG Raster and not of any other format is modified.
