cups-filters 1.22.6 released!

[Till Kamppeter <till.kamppeter@gmail.com>]

Hi,

I have released cups-filters 1.22.6 now, with the following changes:

	- rastertops: Fixed PageSize settings in the PostScript output
	  (Must be in points not in pixels).
	- pdftops, mupdftoraster: Produce actual grayscale/monochrome
	  PostScript (and not only instructions to print grayscale/
	  monochrome) for jobs to be printed in grayscale/monochrome
	  (Issue #96, Pull request #115).
	- mupdftoraster: Fixed filter not producing output at all.
	- Build system: ENABLE_DRIVERLESS got only defined with CUPS
	  1.6 and newer, not with older CUPS versions (Issue #111).
	- pdftopdf, imagetopdf, imagetoraster: Silenced compiler
          warnings.
	- cups-browsed, driverless: Replaced httpConnect() calls by
	  httpConnect2() calls as the former CUPS library function is
	  deprecated.
	- Build system: Compile everything using the CUPS libraries
	  with '-D_PPD_DEPRECATED=""' for the time being until the
	  deprecated PPD API calls get replaced, to stop the flooding
	  with PPD API deprecation warnings making more important
	  warnings being overlooked.
	- cups-browsed: When removing a local queue on shutdown or
	  when DNS-SD reports the printer as disappeared check whether
	  the local queue got overwritten by an external process as
	  sometimes the shutdown or disappearing event comes too close
	  for cups-browsed receiving a printer-modified notification
	  from CUPS before (Ubuntu bug #1731417).

Bug fix release, to address a further issue of cups-browsed removing 
user-created print queues, to make grayscale/monochrome PostScript jobs 
of colored input file actually output grayscale/monochrome files, to fix 
several bugs when using MuPDF as PDF renderer, and to silence compiler 
warnings.

Please release this on Debian so that I can sync it into Ubuntu.

Thanks in advance.
