Update to version 2.0.1

For pkgsrc, rename pkgsrc directory from "tk-tkimg" to "tkimg" to
match actual package name being built, more consistency with other tk
packages, and slightly less redundancy.

Note this package includes other builtin libraries (jpeg png
tiff zlib) that are part of the source distribution.  I don't think
there is an easy way around this issue.

Also, the previous version (tkimg-1.3.20080116nb5) built for me but
wouldn't run on NetBSD as there seemed to be tcl errors about not
being able to load the Img package (i.e., tkimg, this package)
========================
2024/12/08: Version 2.0.1
Maintenance release.

    Added --with-tk8 configuration option.
    Improved tests handling PS and PDF format.
    Removed test suite afltests from distribution files, as it contains image \ 
files triggering virus alarms at VirusTotal.

2024/09/30: Version 2.0.0
Major rework. Tk 9 support.

Support for Tk 9 based image metadata:

    Added ability to read and write metadata via the new Version3 match, read \ 
and write functions as defined in TIP 529.
    The following metadata information are currently supported for read and \ 
write functions: DPI, aspect.
    Added options -resolution, -xresolution and -yresolution to image formats \ 
BMP, JPEG, PCX, PNG and TIFF to allow writing resolution information into image \ 
files without setting the correspondig metadata explicitely. These options work \ 
with Tk 8.6, too.
    See chapter Image Metadata of the Img reference manual for more details.

Further improvements and changes:

    Extended and improved test suites.
    Extended and improved documentation.
    Added Img homepage including reference manual.
    Removed all stuff related to Tk < 8.6.
    Do not support base64 encode image data anymore, as this feature made \ 
auto-detection of image formats not working correctly. Either use GIF or PNG \ 
format for base64 encoded images, which can be read by Tk or use the binary \ 
encode/decode command.
    Match functions for JPEG, PNG and TIFF now use related library functions \ 
instead of hand-crafted file header parsers.
    Format handler for PS and PDF does not hang anymore.
    Unified and corrected handling of format options. All format handler now \ 
support the -verbose option.
    Several security and stability related changes.
    Updated external libraries: JPEG 9f (9.6.0), PNG 1.6.44, TIFF 4.7.0, ZLIB 1.3.1.

Incompatible changes:

    Img version 2 only works with Tcl/Tk 8.6 or newer. If using an older Tcl/Tk \ 
version, use the lastest Img 1.4 version.
    No base64 encoded image data support anymore.
    Syntax of option -resolution for format BMP has changed.
    All optional values specified when writing PNG files were interpreted as \ 
text metadata. Text metadata for PNG files must now be specified explicitely \ 
with new option -tag.
    Format GIF must be explicitely loaded with package require img::gif.
    The default resolution values written have been unified:

Format   Old Value   New value
------------------------------
BMP             74           0
JPEG             0           0
PCX            300           0
PNG              0           0
TIFF          1200           0
