Correct a long standing problem that caused non-optimized builds with
MSVC on Windows. The default TDEBUG was 1, which circumvented a change
made to msvccmd.mak to enable /O2 for MSVC_VERSION != 5. Note that
with MSVC 6 Service Pack 3 is required to avoid an INTERNAL COMPILER
ERROR when compiling src/idict.c.

performs that check perfectly.

In the autoconf build, add the general cflags generated by the configure script to the definition
the the definition of CCAUX. This works around a problem building on cygwin.

DETAILS:

Older versions of cygwin do not provide stdint.h but do define some of the types in sys/types.h.
More recent versions do provide the header but also define them by inclusion in sys/types.h. This
caused a problem with the 'fixup' code we added in response to bug 687162 which defined the
missing half of the types if stdint.h was not detected by the configure script. In versions of
cygwin that do provide stdint.h, most files compile as expected, but genconf.c is compiled with
the alternate CCAUX compiler definition and was not receiving the -DHAVE_STDINT_H argument from
configure, causing a type conflict between the complete set of stdint types pulled in by
sys/types.h and the platform-specific fixup set included when stdint.h is supposedly not
available. Adding the GCFLAGS line to the definition of CCAUX works around the problem and has
little potential to confuse the build in the future.

A similar change made to unix-gcc.mak would need to document the -DHAVE_STDINT_H option for
cygwin. I felt this was unecessarily excessive; we already recommend the autoconf build on systems
that can support it.

DETAILS :

Side bearing and width was accounted before import_shift is adjusted to FontBBox.

Besides that, it prevents a fixed overflow when FontBBox is zero and glyph coordinates are big.
Bug 687175 "(type 1 hinter) A fixed overflow can happen".

Instead that it dynamically reduces the number of fraction bits

Remove the search for long long / int64_t from genarch entirely. Neither of these

Generailze the trapezoid fillling algorithm for curves, step 1.
The new code is disabled with CURVED_TRAPEZIOD_FILL 0 in gx.h .

DETAILS :

This patch slightly changes the enabled code
with adding more arguments to process_h_lists and end_x_line,
and with renaming gx_flatten_sample and gx_path_is_monotonic.
The new arguments are not used with CURVED_TRAPEZIOD_FILL 0.

With CURVED_TRAPEZIOD_FILL 1 the trapezoid filling algorithm
doesn't need to faltten the path in advance, and should work faster
due to smaller number of segment allocations.
Instead the generating of flattened segments and storing them to RAM
it breaks curves into pieces on-fly with help of
the gx_flattened_curve_iterator. Meanwhile it needs "small" curves.
To provide that we generalized gx_path_is_monotonic to gx_path__check_curves,
and gx_path_add_monotonized to gx_path_copy_reducing(..., pco_small_curves).

Minor changes :
- Fixed the vd_curve macro;
- improved vdtrace calls in gxpflat.c;
- Moved the FLATTENED_CURVE_ITERATOR definition to gx.h .

Add a fallback definition of the common fixed-sized stdint types based on
the type sizes in the generated arch.h header. This should improve the portability
of uses of these types within the Ghostscript source.

DETAILS:

This new code in std.h does not superceed the in stdint.h and similar platform-
dependent includes in stdpre, it merely provides a fallback. stdpre.h now defines
STDINT_TYPES_DEFINED if it has done so; the std.h code is only activated if this
preprocessor symbol is not set.

This change does not help with the portability of compiling jbig2dec directly as
part of the Ghostscript build system since that code as a separate library includes
no headers from the Ghostscript tree.

Fix for 687020 and 687146.  The pdfwrite device is incorrectly converting
CalRGB color spaces into ICC color spaces.  Fix #1.

Details:

As Raph pointed out in the Wednesday's support call, there are actually
two problems.

1.  We were not correctly recognizing that we can use a CalRGB color space
for the output.  This patch corrects this problem.  One of the tests in
that process was assuming an incorrect ordering to the transforms.  This
fix corrects this problem.

2.  The ICC color space which is being created is not equivalent to the
original CalRGB color space.  This results in differing colors between
the original file and the output PDF file.  This problem is still open.

Note:  I am leaving these bug reports still open since problem 2 is still
open.

Factoring out the iterator for flattened curve segments.

DETAILS :

The new code is marked with FLATTENED_CURVE_ITERATOR defined in gzpath.h.
It defines gx_flattened_curve_iterator for using in the True Type grid fitting.

The old code has bugs in the MERGE_COLLINEAR_SEGMENTS section.
An uneven behavior happened near the 'points' buffer boundary
and with the last but one point : some points were not skipped
when they should. For a while we keep a compatibility of the
new code to the old one.

This patch :

1. Defines of the gx_flattened_curve_iterator.
2. Emulates of the old code with gx_flattened_curve_iterator.
3. Provides a compatibility to the old code bugs with FLATTENED_CURVE_ITERATOR0_COMPATIBLE.
4. Improves a debug printing in the old code, to allow a trace comparizon with the new one.
5. Improves an old comment "Fast check for n == 3" ('n' was not explained).
6. Saves stack space when gx_flatten_sample recurses.
7. Inserts a 'const' into vdtrace.* .

Replace the code that removes the additional CFLAGS added by the AC_PROG_CC autoconf
macro. Closes bug 687150.

DETAILS:

On linux with gcc, AC_PROG_CC adds '-g -O2' to the general CFLAGS. This was overriding
the -O we add in Makefile.in, and the bug complains that this confuses gdb because of
code re-organization.

This change also means we no longer include full debug symbols in the normal build. I
don't consider this an improvement personally, but will bow to the traditionalists. Note
that 'strip' still reduces the size of the executable by 20%, so it's still worth
running if you're concerned about install-size.

Fix (pdfwrite) : Numeric errors appeared writing an UCR.

DETAILS :

The old code wrote UCR (undercolor removal) functions with mapping 0 to 0.00392,
causing a solid black to convert to a non-solid color with pkmraw device.
The fix reduces the sample range to [0:254] and generates an appropriate Decode array.

Bug 687109 "PDF-->pkmraw: 0 0 0 RG isn't solid:.
Bug 687138 "pdfwrite is adding poor UCR functions to output files".

EXPECTED DIFFERENCES :

This patch causes multiple differences with pdfwrite->pkmraw.
The change to pdfwrite definitely is a progression,
but it discovers a new bug 687146 "(pdfwrite) CalRGB wrongly converts to ICCBased".

We did not check which differences are coused by the new bug.
Will see after the bug is fixed.
Updating the baseline should be fine for entire list.

JAWS PDF generator encodes empty stream as jaws_empty[]. The stream declares
that the data block length is zero but zlib routines regard a zero length data
block to be an error. Check for this case and return EOF without calling zlib.

Fix : The first clip path list element sometimes got an empty path.

DETAILS :

This continues fixing the bug 686885 "bad paths in pdf".

If !pcpath->path_valid, we convert the pcpath->rect_list to a path,
storing it into the clip path list element.

a difference with Altona-Testsuite_p2_S_x3.pdf was misidentified as a progression.
Rather that raster looks better, it differs more from Adobe.
With this patch the raster is closer to Adobe)

Fix: Adobe Acrobat Reader ignores an empty path when setting the clip
path. Bug #687136.

DETAILS:

We never encountered this problem in a 'real' file, but one of Raph's
test files showed the difference in the way our PDF interpreter handled
an zero area path to setting clipping versus the way Adobe does.

Igor tested CPSI and determined that PostScript results in a zero area
clipping box, but Acrobat Reader works differently, so the patch detects
a zero area path and does not change the clipping path in that case.

The details of the determination of 0 area is commented here:

pathbbox	% get the path bounding box
3 -1 roll	% roll to get upper and lower Y coordinates together
sub abs		% form absolute delta Y of path bbox
3 1 roll	% roll upper and lower X coordinates to TOS
sub abs		% form absolute delta X of path bbox
add		% sum abs delta X and abs delta Y
0 ne		% if it is non-zero, then perform the clip/eoclip

Fix (pdfwrite) : Transfer function was not checked for identity.

DETAILS :

Bug 687124 "Large PDF file created from Quark with EPS's within",

Fix bug 687135

[lib/pdf_sec.ps 1.12]

2003-11-12 14:29 Igor Melichev

Fix (pdfwrite) : Write high level clipping paths.

DETAILS :

This includes the "Preliminary patch for preserving clip path lists-bug686885" by Raph
(gxcpath.c, gzcpath.h), and a simple algorithm for writing it to PDF (gdevpdfd.c).

Now it writes entire list whenever clipping path is changed.
A diserable optimization is to avoid writing redundant elements.
For doing that we would like to have an id and a 'changed' flag in gx_path_s.

Bug 686885 "bad paths in pdf".

EXPECTED DIFFERENCES :

Use [/XYZ null null null] as a default destination following the Distiller
example. The old destination was clearly wrong because it positioned the

Fix bug 687129

[src/gdevpdfm.c 1.33]

2003-11-11 11:23 Igor Melichev

Fix : ..includecolorspace caused an abnormal recursion.

DETAILS :

1. With -dNOSUBSTDEVICECOLORS the procedure ..includecolorspace called
setcolorspace, which recursively called ..includecolorspace .
This recursion would be infinit unless an ocasional error
in a stopped context terminates it. We replace setcolorspace
with _setcolorspace_nosub to avoid the recursion.
This fixes the bug 687134 "-dNOSUBSTDEVICECOLORS causes text to disappear".

2. An optimization done with a new dictionary ..page_default_spaces,
which now keeps up to 3 global flags for Default* color spaces,
to reflect whether they were included into a current page.
It prevents redundant calls to _setcolorspace_nosub, .includecolorspace
from ..includecolorspace .

3. Moved .PurgeDict to gs_init.ps because now it is called from showpage, copypage .

4. Added a name argument to .includecolorspace and passed it through
a set of functions in the graphics library and pdfwrite.
Before that Default* color spaces were included into the PDF output
with wrong resource names.

5. Minor change : fixed a procedure header comment in gs_devcs.ps .

EXPECTED DIFFERENCES :

None, because the nightly regression doesn't test -dNOSUBSTDEVICECOLORS .

Fix (type 1 hinter) : Hints were not applied to the last segment of a Type 2 glyph.

DETAILS :

Due to Type 2 glyphs have no explicit closepath,
the last contour was not added to the contours list.
It caused its last segment got type=closepath instead type=oncurve,
and was skipped from grid fitting.

Fix for 686796 tiffg4 device and incorrect halftone frequency.
This eliminates a problem with not choosing the best halftone cell size
when more than one possible cell size has the exact angle requested.

DETAILS:

Previously the logic for determing the size of the halftone cells used
the product of the error in frequency times the error in the angle as
the metric for determing the best cell size.  For many common angles,
0, 45, 90, etc., this results in an angle error of zero.  This then
gave a value of zero for the metric no matter what the frequency error.
The result was that in many cases we ignored cell sizes that gave a
better frequency match.  The fix revies the metric to choose a cell
size which is closest (geometrically) to the ideal cell size.

2003-10-31 22:12 Igor Melichev

Fix (font resource machinery) : Provide correct font names for graphics library.

DETAILS :

The old code passed names of substitutes rather than font names referred by a document.
This patch fixes that with adding a special ney entry /.Alias to the font dictionary.

Besides that, multiple problems are fixed in gs_fonts.ps,
some of them appeared before the repository was created.
Lising them here :

1. Several comments about stack layout in procedure headers were wrong
   since the repository was created.
   We repaired some of them, but possibly not all.

2. The old code assumed that SubstituteFont adds
   a name to the stack rather than replaces it.
   See comment inserted into .dofindfont .
   The patch for the bug 637424 (Revision 1.24, Nov 21, 2002) broken the
   old behavior and left multiple rudiments in code.
   Now we restore the old functionality, and make SubstututeFont
   to be compartible with CPSI, which replaces a name.

3. Now we define fonts for all aliases in the aliasing/substituting chain.
   Not sure it is better than defining only the final one,
   but the pre-repository code did so, and was
   unintentionaly broken by multiple patches.

4. .stdsubstfont dropped some aliases with no strong reason.
   Restoring the old behavior.

5. .tryloadfont damaged the stack balance. It was not visible due to (4).

6. We use a hack to provide the main functionality.
   See comment in .aliasfont . A complete solution is too hard.

7. Inserted auxiliary comments about the stack layout.

This change fixes the bugs
687047 "fonts renamed in resulting pdf file"
687111 "Quality of output wth gs8.11 for pdfwrite device is faded as compared to gs6.12"

EXPECTED DIFFERENCES :

MANY OF pdfwrite TESTS RENDER DIFFERENTLY due to the font substitution had changed.
Now pdfwrite does not embed /NimbusMonL-Regu, but recognize its alias Courier
as a standard font name.

Fix (garbager) : The back pointer validity constraint was wrong.

DETAILS :

Bug 687021 "A crash in memory manager"

Here is what happens :

A big chunk is allocated by i_alloc_struct_array.
Later a part of the array is released.
Then another object is allocated in the released area.
Then the object is being relocated.
The old validity constraint in igc_reloc_struct_ptr assumed that the object
is in a chunk of the standard size.
However it is not.
The check fails, and gs_exit() is called.
The latter calls vm_reclaim and falls into an infinite recursion and crashes.

This patch enhances the constraint for instandard (big) chunks.
Unfortunately their sizes can't easy obtain from igc_reloc_struct_ptr,
therefore the new check only works for pointers to same chunk.
A new field (DEBUG=1 only) is inserted into gc_state_s to access the chunk from
igc_reloc_struct_ptr. We're not happy of this solution,
but there is no idea how to improve it.

EXPECTED DIFFERENCES :

Fix (PDF interpreter) : Shared CID font descriptors did not work properly.

DETAILS :

When a CID font descriptor is shared with several CID font resources,
must create several font objects with different CIDToGIDMap, DW, DW2
taken from CID font resource dictionaries.
The old code created a single font object with one randomly chosen CIDToGIDMap,
making some glyphs inaccessible, and glyphs could misplace.

New procedures adjustCIDType0, adjustCIDType2 are added into the adjustfont
dictionary, so that now CID fonts are processed in same way as fonts.
Bug 687048 "fonts not rendered correctly".

Besides that, the old code on pdf_font.ps created a CDevProc
for processing DW[2], but it was not properly added to the font dictionary and
was not executed. The new code fixes that.
This issue causes rendering differences.

I found several pdf files with damaged or incorrect annotations (outlines, links)

When using the pdf interpreter with -dDOPDFMARKS, such
errors cause an execution error in the pdf interpreter
The attached patch ignores such errors.  The assumption is that
it is better to produce botched pdfmarks than producing an error

Fix : Disable the grid fitting while charproc accumulation.

DETAILS :

This is a partial (minor) fix for the bug 687087 "pdfwrite : A mangled /trademark glyph".
The glyph looks fine but still converts to outline.

This change works for pdfwrite only.
It changes several files in the graphics library, but other devices
should percept this change as algorithmically equivalent.

The core of the change is explained in the comment inserted into gdevpdtt.c :

    if (pdev->font3 != 0) {
	/* A text operation happens while accumulating a charproc.
	   This is a case when source document uses a Type 3 font,
	   which's charproc uses another font.
	   Since the text operation is handled by the device,
	   the font isn't converting to a raster (i.e. to a bitmap font).
	   Disable the grid fitting for the convertion to get a proper outlines,
	   because the viewer resolution is not known during the accumulation.
	   Note we set identity CTM in pdf_text_set_cache for the accumilation,
	   and therefore the font may look too small while the source charproc
	   interpretation. The document tpc2.ps of the bug 687087 is an example.
	*/
	penum->device_disabled_grid_fitting = true;
    }

It is implemented with defining the new field device_disabled_grid_fitting
into gs_text_enum_common.

Minor changes :

1. In gs_type1_state_s renamed charpath_flag to no_grid_fitting.
   We believe the new name reflects the semantics better.
   Several function prototypes changed the argument name.

2. decompose_matrix in gxttfb.c changed the prototype,
   and disables the TT grid fitting for very small fonts.
   (We consider it as a minor change, because currently this portion
   is disabled with NEW_TT_INTERPRETER 0 in gx.h).

3. A problem discovered in t1_hinter__set_mapping that
   impedes implementing a grid-fitting disabling for small Type 1,2,11 fonts.
   A comment is inserted into gxhintn.c about that.
   Very samll glyphs can be mangled diring a rasterization, but the mangling
   isn't visible in raster with such small sizes.
   Therefore the problem isn't important.

EXPECTED DIFFERENCES :

None with comparefiles.

The test file tpc2.ps of the bug 687073 doesn't cause a mangled glyph,
rather the glyph still converts to outline.

Return correct /DeviceGray color space from currentcolorspace operator
inside PaintProc of the uncolored pattern and cache device (bug 627169).
Use igs->color_space to track the current color space.
Fix bug 687080 from customer 710.

DETAILS:

The problem in bug 687080 is definitely a conflict about the current
color space while the PaintProc is being executed.  There are two
color space indicators: pgs->color_space and igs->colorspace.  Most
of the time these two agree and there is no problem.  However during
pattern accumulation pgs->color_space has been temporarily changed
from a pattern color space to DeviceGray.  This causes a problem
when the currentcmyk operator is called.  Currently, before this fix,
it calls currentcolor which returns a DeviceGray color.  Then a
color to CMYK routine is called based upon the color space being
a pattern color space.  This then fails since it has the wrong input
color values.

The fix looks at the current color space, in pgs->color_space,
and is special casing DeviceGray.  The fix should work better than
the current logic.  The only problem area would likely be if we have
other 'temporary' color spaces besides DeviceGray.  I do not know of
any and the current logic would also fail.

Fix: Pattern color spaces that used save/restore within the PaintProc
would result in infinite looping with high level devices such as the
pdfwrite device since the restore cleared the pattern cache so that
after the restore, the pattern PaintProc would need to be executed
again. Bug #687052 for customer #411.

DETAILS:

The 'is_dummy' flag in the pattern cache indicates that the cache
entry does not contain bitmap or tile bits, but rather is just
a placeholder for the pattern 'id'.

The patch does not delete entries for pattern color spaces that
have is_dummy != 0. The pdfwrite device creates all pattern cache
entries as dummies.

This change does not result in any regression and, of course, prevents
the infinite looping.

In a code review for the NOSUBCOLORSPACES switch, Igor suggested changing
the name to KEEPDEVICECOLORS.  I still prefer NOSUB instead of KEEP.
Basically I prefer that switches which stop an action begin with NO.
However changing COLORSPACES to DEVICECOLORS is a definite improvement
since COLORSPACES is overly general and thus inaccurate.  The only

DETAILS :

This completes the fix for the
bug 687054 "pdfwrite should include DefaultGray, DefaultRGB, DefaultCMYK".

The "default" color space resources are being included only if all 3 conditions are satisfied :

1. -dUseCIEColor is set;
2. -dNOSUBCOLORSPACES is set;
3. The source document defines the resource.

If the document doesn't define the resource, but the user wants to include it,
the document to be prepended with

  currentglobal true setglobal
  /DefaultGray /ColorSpace 2 copy findresource exch defineresource pop
  /DefaultRGB  /ColorSpace 2 copy findresource exch defineresource pop
  /DefaultCMYK /ColorSpace 2 copy findresource exch defineresource pop
  setglobal

and the resources must be available in gs/Resource/ColorSpace.

Fix (PDF interpreter) : Adjust the currentpoint saved back into TextMatrix so that it
does not include the effect of TextRise.

DETAILS :

Bug 686837 "PDF with subscript rendered wrong"
Patch from Raph Levien.

Here is analyzis from Raph Levien :
[beg quote]

the test file is using PDF's Ts operator to adjust the
"text rise", exactly as shown in section 5.2.6 "Text Rise" of the
PDF manual (3rd ed). Ghostscript's rendering is incorrect because
the "settextposition" function (in pdf_ops.ps) updates the TextMatrix
using the current point after showing the text. However, this point
already contains the effect of TextRise. Then, the next time
settextmatrix is invoked, it applies TextMatrix, followed by a
second TextRise.

The patch below simply reverses the effect of TextRise before setting
TextMatrix. I believe that the correct invariant is that
"settextposition" followed by "settextstate" should result in (0, 0)
being the current point in the resulting CTM. I argue that the patch
fulfills the invariant, as follows. Let the current point be (x, y),
relative to TextSaveMatrix. Then, settextposition sets the translate
portion of TextMatrix to (x, y - TextRise). Then, settextmatrix (as
invoked from settextstate) applies TextMatrix followed by TextRise,
for a net translation of (x, y).

Query: is this reasoning still valid for arbitary rotations and scales
in TextMatrix (as set by Tm)? It seems so to me, but I believe testing
is required to establish this definitively.

This patch applies the design grid to emulate an infinite resolution with GridFitTT=0.

The old code literally implemented the Raph's idea to disable the pixel rounding in the

while coordinate computations with low level TT operations.

This patch implements a new user parameter GridFitTT.
A change to documentation isn't supplied because

If a font initialization program doesn't use patented instrictions,
and some glyphs of the font uses patented instructions,
the glyphs renders without a grid fitting, and a warning is printed to stderr.

If a font initialization program doesn't use patented instrictions,
and a glyph of the font doesn't use patented instructions,
the glyph renders with grid fitting, and no warning is printed.

Note that some font may mix both grid-fitted and non-grid-fitted glyphs.

GridFitTT=0 forces the TT interpreter to skip the grid fitting.

This is part of the fix for 687055.  This change splits the DeviceN
parameter handling.  The SeparationOrder parameter handling is split
into a separate routine.

DETAILS:

The DeviceN parameter SeparationOrder is used to select which separations
are to be included in the output.  This parameter is not appropriate for
high level devices like pdfwrite.  The pdfwrite device does not attempt
to separate its output into separations.  However the pdfwrite device
does use its process color model colors for specifying output colors in
some backup cases.  If a separation were missing then the it would create
an incorrect output color. By splitting out the SeparationOrder parameter
we can still use common routines for pdfwrite and other DeviceN output
devices.

Fix (pdfwrite) : Don't use Tj when real width is smaller than 1% of Widths.

DETAILS :

This is a workaround for the bug 687051
"freehand patterns cause incorrect result".
See comment in code.

Our workaround is hewristical.
To get a strongly guaranteed result a bug to be reported to Freehand,
which sets a wrong character size with setcachedevice :
the setcachedevice arguments appear 144 times bigger when the actual glyph size.
After converting to PDF it causes too big numeric errors in a PDF viewer.

Adobe Distiller converts this text into a paintings of
individual glyphs, loosing the text features, and enlarging the uncompressed output.
The Adobe's method appears acceptable with this document
because the text actually represents a texture, and the text features (Encoding, etc.)
appears unimportant. We can't implement the Adobe's method because we have no idea
how to recognize in pdfwrite the case of a Type 3 font represents a texture.

Users may want to apply an idiom recognition in PS level for that texture,
to convert it into a regular images for a better coordinate precision.
The ideom approach is independent to this patch, and we believe that
both things can work togeter.

Don't apply Type 1 hinting to charpath.
THIS IS AN INCOMPATIBLE CHANGE : charpath now creates a different outline than before.

DETAILS :

Adobe doesn't hint charpath.
Not sure why GS did.
This change makes GS to be closer to Adobe and
partially fixes the bug 687044 "strange elements with text".

Note that 'charpath fill' never was equal to 'show'. Neither the old hinter,
nor the new hinter, nor any combination of them in the pair ('charpath', 'show')
give same result. This happens because 'fill' uses the "center pixel inside" rule,
but 'show' uses a different one. With the new hinter 'show' performs
a spot topology analyzis during the rasterization. This rule doesn't belong
to the class of rules, which can be explained in terms "a part of pixel inside".

Thus, since "same" or "closer" result isn't possible,
the criterion for the choice must lie in another space.
I believe that the "Adobe compatibility" is the right one.

Besides that, Ghostscript PDF imperpreter emulates the text rendering modes 1,5,6
with 'charpath stroke', and with the hinted charpath the results look strange.

Provide a means for disabling color space substitution.

DETAILS:

Ghostscript supports substituting CIE and ICC color spaces for DeviceGray
DeviceRGB, and DeviceCMYK color spaces.  This is part of the support for
the UseCIEColor feature in PostScript.  This substitution is done inside
the PostScript code in lib/gs_devcs.ps.

The recent improvements to the pdfwrite device mean that the interpreter's
color space and color values are now passed to the output file.  Since
the color space substitution is done prior to passing the color space to
the interpreter, the original color space is lost if UseCIEColor is
set.  This change provides a means to prevent the substitution.  Thus
the original color space is passed to the interpreter and on to the
output file for pdfwrite.

If the color space is new, it needs a complete serialization
for storing the data to PDF resource. We can't delay the serialization
because the life time of the original color space may exceed before
the next comparizon happens. Contrary, if the color space is not new,
it also needs a complete serialization for a full comparison,
to know whether it is same color space.
Thus, a complete serialization is required in any case.

This stuff will be used by high level devices for comparing color spaces.
A serialization will. be used because we need to compare color spaces,
which's life times don't intersect.

This patch only defines new functions but never calls them.
Regressions should not appear.
A draft implementation for the functions is provided.
A debugging of them will be a separate issue.

Defining a new device virtual function fill_rectangle_hl_color.
This fuction is used to implement gs_rectfill and gs_fillpage
with a high level color handling.

DETAILS :

The old device virtual function fill_rectangle has no way to pass a high level color.
Therefore high level devices always used process colors with rectfill and fillpage.
See gxdevcli.h for the definition of the new function.

The new function is used to implement gs_rectfill and gs_fillpage in pdfwrite.
gs_rectfill and gs_fillpage are modified to provide the new logics.
gdevpdfd.c is reorganised with factoring out some common code parts.

Fixes the bug #687024 "rectfill doesn't pass high level colors to device".

This patch causes a MINOR DIFFERENCE in color in all Genoa tests with pdfwrite :
a gray rectangle in the header gets a sligtly different gray value.

Besides that, the following files render few differently due to coordinate rounding in pdfwrite :

Rename the client header errors.h to ierrors.h. This is more consistent
with iapi.h, and reduces the risk of a namespace conflict. The old
errors.h header is still available, and simply includes ierrors.h
for compatibility. This file is marked as deprecated and will be removed
in a future release.

This change is in response to a spurious report of a namespace conflict on MacOS in bug 686966.

Removing rudiments of the old hinter (step 1).

DETAILS :

This patch encloses rudiments of the old hinter with "#ifdef KEEP_OLD_HINTER",
where KEEP_OLD_HINTER is undefined.

This change is algorithmically equivalent,
because the new hinter worked instead the old one. Only exception is
the change to gstype1.c ln 370 : the condition t1_hinter__is_x_fitting(h)
is waeker than the old pcis->fh.use_x_hints, because
the new hinter applies an X-grid fitting with a slightly sloped transforms.

The change to gdevpsfx.c define local arrays for storing hints.
The old code used the old hinter structures, which appear too heavy
for the need of gdevpsfx.c .

Fix for 686948 Dotted lines messing in PDF.  Draw all line cap
types for zero line lengths.  Previously only rounded caps were
drawn.

DETAILS:

This is a (minor) revision to a the previous fix from Jeong for
this problem.

For those people who do not remember, this problem involves a dashed
line with a zero line length for the imaged (pen down) part of the
dashed line.  Ghostscript currently calls this a degenerate situation
and does nothing except for round line caps.  Jeong had previously
proposed changing the test to any line cap except butt caps.  Jeong
removed this proposal after testing and finding that Adobe Acrobat
drew thin line segments even for butt line caps.

This proposal simply removes the test for line cap type completely.
It does still leaves a test for dot length = 0.

The routine already contains code for using adjacent line segments
to determine a 'direction' for zero length segments.

Testing with both butt and square line caps and with on axis and
diagonal lines produces results comparable to Adobe Acrobat.
(Acrobat is not consistent with segment widths for the butt joints.)

pdfwrite : Implementing a high level color handling.

DETAILS :

pdfwrite now passes colors identically except minor problems,
which should be fixed soon :

1. rectfill still converts colors.
   This happens because gs_rectfill calls dev_proc(pdev,fill_rectangle),
   which doesn't pass device color.
   Therefore high level color is not available for pdfwrite.
   This is an architectural problem which requires a hard decision.

2. Some documents (gs.anotherfailure.pdf is an example) generate
   too many color space objects to the output PDF.
   Requires an optimization.

3. 477-03.ps embeds a color space that can't write to PDF due to PDF limitations.
   Process colors are written into PDF.

4. Few tests cause significant difference in colors :
	0.pdf               (yellow background)
	MagicEye.pdf        (yellow background)
	Fixed_Original.pdf
	Testform.v1.0.2.pdf (a gray rectangle disappears)
   To be analyzed.

A preparation for high level color handling in vector devices.

THIS IS INCOMPATIBLE CHANGE for devices derived from gx_device_vector.
Now they must implement the new virtual function can_handle_hl_color.
A simplest impementation compatible to the old behavior is to return false.

DETAILS :

The new code uses the new functions gx_hld_save_color and
gx_hld_saved_color_equal instead the old gx_saved_color_update.
This allows devices to know when the client color changes and
to generate the appropriate output. This affects
pdfwrite, pswrite, epswrite, pxlmono and pxlcolor devices.
However the devices still write device colors to output.
An implementation of writing the client color
in pdfwrite, pswrite, epswrite will be the next improvement.

Since a big part of color code is shared with pxlmono and pxlcolor,
we need a switch for checking whether the device can handle
high level colors. For this purpose we add a new
virtual function can_handle_hl_color to gx_device_vector_procs.
Currently all implementation of this function return false,
and all devices still write process colors.

A minor change : psdf_setfillcolor and psdf_setstrokecolor
are removed because they were never called.

DETAILS:

On page 493 of the PDF 1.4 reference, NoView is specified as bit

However, for some reason Adobe counts its bit positions starting at

are left for further developmant. We intend to convert the filling algorithm into
a template like we did with gxdtfill.h . The goal is to generate
several instances of the algorithm optimized for different cases :
a non-character fill (with the path adjustment and with no dropout prevention),
character fill (with no path adjustment and with dropout prevention),
and spot topology analyzis for autohinting (no adjustment, no dropout prevention,
store trapezoids into a special storage). The ADJUST_SERIF code
probably will die after True Type hinter is done.

device colors to include the high level color values used to create
the device color.  A flag was also added to indicate if the color
information (in dev_color->ccolor) is valid.  There are also two

Fix for 686998 syntax error in findxref for customer 580.  The given
test file does not have 'startxref' on its own line.  This is a
violation of the PDF spec.  However Adobe Acrobat accepts the file.
This fix adds a check for this case and prints a warning message.
File processing then continues.

DETAILS:

This fix also includes moving the findxref inside of a stopped context
check in case any other problems are encountered while searching for
the xref table.  If a problem is now found during findxref, the xref
rebuild logic will be called.

The invocation "./configure; make install" wasn't working because
the install target doesn't create the "standard directories", in
particular obj/. This patch simply adds the STDDIRS dependency to
the install-exec target, parallel to the existing std target, which
is the default chosen from a simple "make" invocation.

Fix non-conformance of "startjob" if password check fails. Previously, the
"quit" operator in systemdict was masked by a definition of /quit as /stop
in userdict, even if startjob failed due to password check or other reason.
