This will allow to use the official Windows installer directly in the
Windows Store, as per the new proposed workflow by Microsoft.
Nevertheless our GIMP for Windows has a built-in update check which
would check if a new version exist and warn people (advising them to go
on the website and download the new installer to update). We obviously
don't want this on the Windows Store which has its own update channel.
It would be confusing.
Therefore I added a feature to disable the built-in update check (not
even showing in Preferences) by tweaking a single package variable. The
installer now comes with new option /DISABLECHECKUPDATE=true which will
add said variable.

GIMP was saving the last changed/saved date to IPTC tag DateCreated,
which should only be used for the original creating date of the image
and thus should not be changed by GIMP.
After discussion in the cited issue, there is no tag in IPTC that we can
use, so we remove saving modified date from the IPTC metadata.
Instead we add two XMP tags, one for modified date and the other for the
date that metadata was changed. Since we do both when exporting, both are
saved with the same date/time in ISO 8601 format.
This also fixes another issue where we were not storing the timezone offset
for Xmp.tiff.DateTime. Since this has the same format as the other
XMP tags, we fix this together with this issue.
… in the gimp-release file.
This will be useful to disable the update check for the Windows Store
even though we use the same build as the installer. All it will take
will be to append the line `check-update=false` to the file
`share/gimp/2.10/gimp-release` and it will behave as though the update
check is disabled (even though it is actually built-in).

More safety checks for detecting broken xcf files, also based on examining
issue #8230.
After reading an offset where layer, channel, etc. data is stored, we
add a check to make sure that offset is not before where we read the
offset value. Because the data is always written after the offset that
points to it.

Improvements in loading broken xcf files, based on examining issue #8230.
Besides checking for a minimum width and height, GIMP also has a maximum
size we can and should check.
In the case of the image itself, we change invalid dimensions to a size of
1 in hope that the individual layers etc will have the correct size.
For layer, we will also try to go on, but for channel and layer mask, we
will give up.

gimp_channel_is_empty returns FALSE if channel is NULL. This causes
gimp_layer_invalidate_boundary to crash if the mask channel is NULL.
With a NULL channel gimp_channel_is_empty should return TRUE, just like
the similar gimp_image_is_empty does, because returning FALSE here
suggests we have a non empty channel.

Adds a new option to flip the image on export. This allows for
direct imports into certain DirectX engines without altering the
project file. It also adds a new option to save all visible layers on
export, again to avoid altering the user's project file.
Backports option from master to toggle whether IPTC and thumbnails
are saved on export. Note that in webp format, IPTC data is saved
via XMP, so if XMP is not saved, IPTC option is deactivated.
JXL import is backported from GIMP 2.99
Added .jxl association for Windows installer
It was necessary to adjust plugin-defs.pl for HEIF plugin,
because necessary dependencies were missing there.
With large image sizes a 32-bit int is not enough for the intermediate
computations, which byte per pixel, width and height are.
So, just like the function below it does: gimp_gegl_pyramid_get_memsize,
we will cast these to gint64.
Thanks to Massimo Valentini for finding the cause.

Removal of the snprintf define was also part of the UCRT Windows patch
in MINGW. Although it builds fine without this change, there is no need
anymore to redefine snprintf. In addition, I seem to remember that
_snprintf had a shortcoming.
So let's remove the Windows specific code, since it works fine without it.

The UCRT environment is a successor to the MINGW environment on Windows
with a more modern C runtime library.
Building under UCRT we get this error:
../../gimp/plug-ins/file-raw/file-darktable.c:420:7: error:
function '__p__environ' is initialized like a variable"
To fix this we use the relevant part of patch 6 from:
https://github.com/msys2/MINGW-packages/tree/master/mingw-w64-gimp
(cherry picked from commit ef817dc452)
when Offset and Dimensions Bigger than File Size.
If we didn't read the exact amount of bytes, the whole image would be
filled with white.
Let's change this, so we read as much bytes as we can, and fill the rest
with white.
