an PNG filter methods. It also can be used to remove unwanted

* Changed ADLER32 checksum handling to only use inflateValidate()
during IDAT chunk handling; it broke iCCP chunk handling.

Version 1.8.8 (built with libpng-1.6.26beta06 and zlib-220.127.116.11)
Fixed "nolib" build (bug report by Hanspeter Niederstrasser).
Make sure we use system-png.h, and not the local file. It is now
possible to build either the regular pngcrush or the "nolib"
pngcrush in the complete pngcrush source directory (use
"make clean" before rebuilding!)
Fixed timing when using "clock()". Sometimes an additional second
was added when the timer crossed a one-second boundary, since
Upgrade libpng to version 1.6.26beta06 and zlib to 18.104.22.168.
Use zlib-22.214.171.124 new "inflateValidate()" function to avoid checking
ADLER32 checksums. Version 1.8.7 did not work when the "-fix"
option was used.

Add SHA512 digests for distfiles for graphics category
Problems found with existing digests:
Package fotoxx distfile fotoxx-14.03.1.tar.gz
Package ploticus-examples distfile ploticus-2.00/plnode200.tar.gz
Problems found locating distfiles:
Package AfterShotPro: missing distfile AfterShotPro-126.96.36.199/AfterShotPro_i386.deb
Package pgraf: missing distfile pgraf-20010131.tar.gz
Package qvplay: missing distfile qvplay-0.95.tar.gz
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.

Version 1.7.85 (built with libpng-1.6.16 and zlib-1.2.8)
Improved reporting of invalid chunk names. Does not try to put
non-printable characters in STDERR; displays hex numbers instead.
Fixed include path for utime.h on MSVC (Louis McLaughlin).
Eliminated "FAR" memory support (it was removed from libpng at version
Disabled the "-already_crushed" option which does not really work well.

* Restored calls to png_set_crc_action() which had been removed from
version 1.7.72 for some testing and inadvertently not restored.
* Changed "fix" internal variable name to "salvage" (still \
set with "-fix")
* Added code to fix/salvage PNG with "bad adaptive filter value" error.
* Avoid calculating CRC during compression trials except for the last trial,
when the output is actually written.
* Fixed a bug with reducing 16-bit images to 8-bit using "-reduce" option.
