Changes:
- cups-browsed: When generating a PPD for an auto-discovered IPP
network printer, create a "ColorModel" option only if valid
choices are reported for it by the IPP printer.
- cups-browsed: Updated PPD file generator for auto-generated queues
for IPP network printers from the CUPS 2.1.x upstream code, so that
floating-point numbers are written in a locale-neutral way
(CUPS STR #4579).
- cups-browsed: When checking whether a queue name already exists
as a locally defined queue, do case-insensitive comparing as for
CUPS printer names are case-insensitive. This assures that
already existing queues do never get overwritten.
- cups-browsed: Added "IPPPrinterQueueType Auto/PPD/NoPPD" directive
to cups-browsed.conf to allow controlling how cups-browsed
creates queues fr native IPP network printers: with PPD, with
System V interface script, or selecting automatically.
- pdftopdf: Center Landscape-oriented jobs correctly on the page
if the "fitplot" or "number-up" options are used (Bug #1284).
- pstopdf: Removed "-dUseCIEColor" from the Ghostscript command line.
In modern Ghostscript versions (9.11 and newer) it is recommended to
not use it with the pdfwrite and ps2write output devices any more.
- imagetopdf: Corrections in PDF output: Let evince display the PDF
with the correct size including margins and let ghostscript not
complain about an invalid xref entry.
- cups-browsed: Do not add options to the System V interface script
which calls sys5ippprinter but set the options as defaults for the
CUPS queue in printers.conf.
- cups-browsed: When auto-generating a PPD-less print queue for an
IPP network printer, determine default page size, unprintable margins,
and color space from the printer via an IPP request.
- imagetopdf: Debug logging should be only controlled by the LogLevel
of CUPS, not by an awkward build time switch.
- cups-browsed: Determine from the TXT records of the Bonjour broadcast
of an IPP network printer whether it has color and duplex
capabilities and if yes, let auto-generated PPD-less print queues
use appropriate command line options to make use of these
capabilities.
- imagetopdf: Make this filter also work with auto-generated PPD-less
print queues for IPP network printers.
- sys5ippprinter: Renamed pdftoippprinter to reflect that it is
once a System 5 interface script and second does not accept only
PDF as input.
- pdftoippprinter: Support also PWG Raster and JPEG as input formats
so that an auto-generated, PPD-less queue for an IPP printer emulates
an IPP Everywhere printer.
