Documentation


Fixes problems:
	- Improve security in a (mostly) backward compatible fashion adding
more flexible file access paths (PermitFile...) as user paramters and adding
the facility to return to NOSAFER mode after running jobs (files/procedures)
in SAFER mode. Also adds a -dPARANOIDSAFER command line option that only
allows reading files from %stdin, paths specified on LIBPATH, FONTPATH and
/GenericResourceDir or /FontResourceDir. Improve security for device related
access to the file system and to pipes by allowing the dangerous parameters
to be locked (for example, OutputFile). The locking is performed after
command line parameters are established. This should address SF bug #474582
and eliminate the need for the RedHat PARANOIDSAFER patch.

rayjj)

Removes the admonishment to update PVERSION and JVERSION from the Makefile
documentation. The build dependencies were removed earlier to reduce user
confusion; they're currently vestigial in expectation of future build
requirements. This is the second half of the fix for sf bug #457838.
(doc/Make.htm [1.36.2.1]: 2001/10/24 22:29:29 giles)

Adds a link to the v7.xx history files. (doc/News.htm [1.90.2.2]: 2001/10/24
22:32:18 giles)

Adds basic autoconf support to the build system. (doc/Make.htm [1.36.2.2],
doc/Release.htm [1.40.2.1]: 2002/01/24 01:30:56 giles)

Adds a new documentation section on display devices along with a basic
description of the x11 devices. (doc/Devices.htm [1.34.2.1]: 2002/01/30
07:36:09 giles)

Minor change from 'search' to 'filenameforall' in discussion about the
wildcard characters in PermitFile... strings. (doc/Language.htm [1.34.2.2]:
2002/01/31 17:36:56 rayjj)

Procedures


Fixes problems:
	- the icclib makefile comments were out of date; the build rule
referred to gs_stdio_h, which no longer exists; the build rule for gsicc.o
referred to icc_h, which was not defined at that point. patch originally by
lpd, propagated from the development branch. (gs.mak [1.5.2.1],
icclib.mak [1.3.2.1], lib.mak [1.53.2.1]: 2001/10/26 00:15:30 giles)
	- Fix for #474544. Corrects inability to convert valid DeviceN tint
transform functions into type 4 functions. Valid operator names were not
being recognized unless the tint transform function had been bound. One of
two fixes required for this problem. Customer #710. (int.mak [1.50.2.1]:
2002/01/17 02:59:35 dancoby)
	- Fix for #474544. This is the second of two fixes required for this
problem. This fix creates a type 0 function which implements a "color cube"
for those tint transform functions which cannot be converted into a type 4
function. Customer #710. Note: There is one more revision planned for this
effort. This revision will make the buildcolorcube operator into a more
general buildsampledfunction. This will allow its use in other situations.

Utilities


Fixes problems:
	- Incorporate patch from Tim Waugh of RedHat to allow ps2pdfwr to
correctly process files with spaces in their names. Peter's earlier fix
missed a few enclosing "'s for output files. Fixes Sourceforge bug #505338.
(lib/ps2pdfwr [1.6.2.1]: 2002/01/22 21:34:04 jackiem)
	- Improve security in a (mostly) backward compatible fashion adding
more flexible file access paths (PermitFile...) as user paramters and adding
the facility to return to NOSAFER mode after running jobs (files/procedures)
in SAFER mode. Also adds a -dPARANOIDSAFER command line option that only

Replaces references of 'FontManagerLib' with 'FontManager' to match the
Universal Headers stub shipped with Metrowerks CW 6.3.
(macgenmcpxml.sh [1.1.4.1]: 2001/11/02 02:31:21 giles)

Disables the 'unused arguments' warning with the Metrowerks Codewarrior 6.3
Compiler. We have many of these by design and it's responsible for a large
number of warnings on that platform. (macgenmcpxml.sh [1.1.4.2]: 2001/11/02

(gdevcgm.c [1.2.6.1], gdevmac.c [1.1.4.1]: 2002/01/25 06:33:09 rayjj)
	- Removes broken x11alpha driver, and installs an alias for x11
under that name, with default parameters changed to support antialiasing.
Fixes SourceForge bug #505692. (gdevx.c [1.8.2.1], gdevxalt.c [1.2.6.1]:
2002/01/30 20:09:26 raph)

Don't allocate memory or call callbacks when display device does not have a
callback function. (gdevdsp.c [1.5.2.1]: 2001/12/18 07:09:17 ghostgum)

Adds IJS driver to Ghostscript. Includes complete IJS version 0.33
distribution. Also includes autoconf patch by Ralph Giles.

PDF Interpreter


Fixes problems:
	- T* applied the leading horizontally when using a font in vertical
writing mode, but the PDF Reference says the leading is always applied
vertically. (lib/pdf_ops.ps [1.17.2.1]: 2001/12/22 07:34:23 masata-y)

Interpreter


Fixes problems:
	- Some gsapi functions were not passing the user_errors argument to
the corresponding gs_main_run_string_* functions, and instead, these
functions were passing 0. (iapi.c [1.1.2.1]: 2002/01/03 20:20:38 jackiem)
	- ifont.h requires gsmatix.h and gxfont.h for clean compilation. Not
having them was a warning on gcc, but an error on Borland CBuilder 5.5.
Thanks to Rod Webster for the fix. Closes Sourceforge bug #474246.
(iccfont.c [1.2.6.1]: 2002/01/09 21:52:04 giles)
	- ReleaseDC was missed in Windows client applications. SourceForge
bug #499903. (dwmain.c [1.6.2.1], dwmainc.c [1.8.2.1]: 2002/01/16 21:07:16

PermitFileControl paths (was setting them to empty arrays).
(lib/gs_init.ps [1.40.2.3]: 2002/01/31 17:39:07 rayjj)

Change the unstopped error handler to print the operand stack in the same
order as the normal error handler, with the top of the stack at the right.

	- Change show_enum pointer enumeration to properly enumerate
underlying gs_text_enum structure. (gxchar.c [1.5.2.1]: 2001/10/26 16:35:25
raph)
	- Image Type 4 images processed with the Interpolate turned on (as
from -dDOINTERPOLATE) left an uninitialized variable that could cause
extensive slowdown. Fix for SourceForge bug #491308 for Artifex customer
671. (gxiscale.c [1.2.6.1]: 2001/12/14 19:16:04 rayjj)
