GraphicsMagick p5-GraphicsMagick: updated to 1.3.40

1.3.40 (January 14, 2023)

Special Issues:

GraphicsMagick really does need some additional productive volunteers. For several years now, the burden has entirely been on me (Bob Friesenhahn). I have been sheparding the project for 20 years already (and contributed to ImageMagick and GraphicsMagick combined for 26 years already). It is not reasonable to expect someone with a full time job (and expecting to retire in a few years) to do all of the work.

Security Fixes:

GraphicsMagick is participating in Google's oss-fuzz project since February 4 2018 due to the contributions and assistance of Alex Gaynor and Paul Kehrer. The issues list is available at https://bugs.chromium.org/p/oss-fuzz/issues/list under search term "graphicsmagick". Issues are available for anyone to view and duplicate if they have been in "Verified" status for 30 days, or if they have been in "New" status for 90 days. Please consult the GraphicsMagick ChangeLog file, Mercurial repository commit log, and the oss-fuzz issues list for details.

Security Fixes:

DCX: Fixed heap overflow when writing more than 1023 scenes, and also eliminated use of uninitialized memory.

Bug fixes:

GetMagickGeometry(): Fix a scaling issue where dimensions could be scaled down to zero.
PCD: Handle writing image with a dimension of 1.
PNG: When writing, use lower-case raw profile identifiers (e.g. 'Raw profile type xmp') because exiftool expects that.
SUN: The sense of monochrome images was inverted. Fix scanline size calculation.
WPG: Fix 20-year old bug in WPG header reading.

New Features:

JXL: Decode and log extra channel information. This information is not yet used.
PCX and DCX: Support writing uncompressed format (use -compress none for no compression).
Added IM1, IM8, and IM24 magick aliases for the Sun Raster format since those are the historically correct extensions.

API Updates:

AppendImageToList() now updates the image list pointer to be the image which was just added. Use GetFirstImageInList() when the pointer to the first image in the list is needed.

Windows Delegate Updates/Additions:

Jasper is updated to release 2.0.33.

Build Changes:

Visual Studio build possible with Visual Studio 2008 - 2022.
Windows Inno Setup installer now installs Microsoft redistributables rather than using a side-by-side DLL configuration.

Behavior Changes:

AppendImageToList() now updates the image list pointer to be the image which was just added. Use GetFirstImageInList() when the pointer to the first image in the list is needed.
