>     Fix (shadings) : The decomposition limit must depend on resolution.

>     DETAILS :

>     This partially improves performance for the test case of
>     the bug 689189 "PDF fails with /unregistered in --shfill--".

>     The old code limits the decomposition of a shading with 1 pixel.
>     It gives a good precision for low resolution devices,
>     such as display with 72dpi. However for high resolution devices the
>     decomposition limit may be bigger, because tinny parts are not visible.
>     Now we make it be dependent on the device resolution.
>     It speeds up the high resolution rendering with quickly varying colors.
>     The worker formula is :

>     	decomposition_limit = float2fixed(HWResolution / 72)

>     With 300 dpi the file "self-intersect2.ps" renders a few worse
>     near the self-intersection. It may be visible when viewing the
>     ppmraw output with a monitor. We think it's a reasonable tradeof
>     for the performance. Actually the monitor performs
>     a significant zoom when viewing "actual pixels",
>     because the monitor's resolution is much smaller.
>     The quality degradation shouldn't be visible with a 300 dpi printer.

>     Support for the CUPS Raster output device in the lib/*.ps files

>     CUPS-related changes, overtaken from ESP Ghostscript:

>     Define option "-dNOMEDIAATTRS" to turn off the default (but
>     unimplementable) media selection policies for setpagedevice. This is
>     used by CUPS to support the standard Adobe media attributes. Without
>     this option the behavior of Ghostscript stays as before.

>     Due to the fact that it is not possible to properly implement the
>     selection policies from a Ghostscript driver, the default policy was
>     changed to "7" (impose) to avoid numerous problems with printing
>     within CUPS...

>     Bug fix:

>     Martin Lottermoser, author of the "pcl3" driver writes in
>     contrib/pcl3/doc/gs-mods.txt, section C1:

>     There is a bug in ghostscript's default configuration for the
>     undercolour removal and black generation functions. It shows up when
>     printing PostScript documents using the RGB colour space ("setrgbcolor" or
>     "sethsbcolor") on a device where the CMYK space is the native colour space;
>     this is the case for pcl3 if you specify "-sColourModel=CMYK". The bug
>     results in black being printed as a mixture of cyan, magenta, and yellow.

>     The bug is simply fixed by replacing the line

>     functionality to easily select the drivers to be built in. Especially

>     Also the OpenPrinting Vector ("opvp", "oprp") and CUPS Raster output
>     ("cups") are included, to have all the three current interfaces (the

>     Notes:

>     Built-in printer drivers for Ghostscript are obsolete. Do not write
>     any new built-in drivers for Ghostscript. Use the interfaces IJS, CUPS
>     Raster, or OpenPrinting Vector for your new printer
>     drivers. Volunteers for moving these third-party drivers into
>     OpenPrinting Vector modules are welcome.

>     Do not compile the contrib/ directory for commercial-licensed

>     - Change the check_dstack macro in dstack.h so it works the same as
>       check_estack in estack.h -- i.e., if the current dstack block is full,
>       call ref_stack_extend and then only return an error if
>       ref_stack_extend fails.
>     - Change the handling of e_dictstackoverflow in interp.c so it works
>       the same as e_execstackoverflow -- i.e., it doesn't try to extend the
>       stack.
>     - Change the implementation of zbegin in zdict.c to work like

>       ref_stack_extend; if ref_stack_extend returns e_dictstackoverflow, pop
>       the operand from the ostack before returning the error code.

>     Committing Raph's wtsimdi device

>     DETAILS:

>     -r600 -sDEVICE=wtsimdi does a performance optimized clist reader that either directly halftones
>     or uses an intermediate rgb buffer to do non-trivial ROPS correctly then post halftones
>     on a per band basis.

>     Uses icc color profiles to convert to device color.
>     Uses wts halftone algorithm.

>     The device reads in a link icc profile from "link.icc", and WTS
>     halftone files from wts_plane_[0123]. It generates a ppm file that
>     can be used to visualize the halftoned file (it is prepared from the
>     CMYK bits in the procedure write_pkmraw_row in gdevwts.c - if an
>     actual device is available, that routine should be modified to produce
>     data for the device).

>       This device _does_ switch on a per-band basis between continuous
>     tone pathways (true branch of the "if" statement in
>     wtsimdi_create_buf_device) and halftone, based on whether there are
>     rops. That is the major point of the work.

>     This is not yet production ready, but is useful for performance and integration work.

>     Known issues:

>     1. Banding only, low res non-banding will crash,
>     the device is intended for printer resolution halftoning, at 600dpi
>     The halftones are designed for 600dpi.

>     2. Color profiles and halftone screens are not in romfs,
>     These need to be copied into the same object/binary directory
>     that the application is in for now.
>     ./pspcl6 and ./wts_* and ./*.icc in the same directory.
>     Failure to find these files will crash.

>     3. Halftone phase not set correctly in halftone band.

>     4. copy_mono doesn't optimize all-0 and all-1 colors as much as it
>     should - it can avoid processing the screen at that point.

>     5. halftone mode implemented only for rgb color model, not CMYK.

>     6. size of band_colors_used[] array is statically determined
