CHANGES IN V1.13.2

        - cupsfilters.drv: Corrected cupsFilter entry for the "Generic
          IPP Everywhere Printer".
        - driverless: Fixes on the man page
        - driverless: Do not error-exit (non-zero status) when run by
          CUPS as backend or PPD generator when no driverless printer
          is found or Avahi not running. When run from thr command
          line, exit status is the same as of ippfind.
        - imagetoraster: Removed (incomplete) PWG Raster support. For
          PWG Raster output we let the rastertopwg filter from CUPS do
          the finalization (mainly adding white pixels at the borders
          to get a full-page bitmap).
        - imagetoraster: Fixed several bugs in the calculation of the
          page geometry
        - libcupsfilters: If the IPP-polled printer has the
          "sides-supported" attribute, determine the need of a
          "Duplex" option solely whether the attribute has a
          "two-sided-long-edge" choice and ignore the "duplex"
          parameter of the ppdCreateFromIPP() function call. This lets
          the more precise information coming from the IPP query
          always be preferred against information from the Bonjour
          record.
        - driverless: When listing printers let the device ID contain
          "AppleRaster" (for Apple Raster printers) and \ 
"PWGRaster"
          (for IPP Everywhere printers) in the "CMD" field.
        - driverless: Added "-T 3" to the ippfind command line. This
          makes ippfind search the Bonjour broadcasts for up to 3
          seconds when searching for IPP printers, raising the
          reliability in finding all of them
