Enable decoder to use more threads.
8bit YUV->RGB conversion is significantly faster
when AVIF_RGB_FORMAT_RGBA format is used,
because libavif can use libyuv to perform conversion quickly.
Prefer faster AVIF_CHROMA_UPSAMPLING_FASTEST when decoding animation.
Encoder speed changed from to 8 to 7.
Recent AV1 encoders got faster,
so it is OK to switch to better compression quality.
Remove obsolete image/avif-sequence mime-type
as it was merged with image/avif.
The moc process already rebuilds the plugin when the JSON file changes, consequently the additional parameter is not needed.

Dynamic exception specification is not allowed in c++-17. The enforcement needs
to be relaxed for the kimg_exr plugin when using openEXR versions older than 2.3.0.
New libavif 0.9.1 apply some very strict standard compliance
checks by default. Unfortunately, it rejects many files made by
libheif-based apps (GIMP, ImageMagick) in the past.
libheif 1.12.0 (released on May 5, 2021) addressed the problem,
but it would be good to extend grace period, allowing other
projects and distributions to upgrade to fixed version.
Allow saving Qt-unsupported variants of ICC profiles, they could be
correctly handled by apps with wider color management support.
Change way how QColorSpace is created to avoid
rare problems in some apps.
It's not a huge problem since QIODevice::seek() is a noop on negative values but it's
just better to bail out as soon as possible when we realize the file is
broken
The formula was found in Qt's qt_pixelMultiplier (qpagesize.cpp)
as called by the deprecated setPaperSize method (when the unit is
DevicePixel)
NO_CHANGELOG
The HDR QImageIOHandler plugin only supports the default image orientation (-Y +X) in .hdr files. It mixes up the width and height however, resulting in non-square images not loading.
This fix adds a check for the standard image orientation in the file and returns false (with error message) if that fails.
If it succeeds, it takes the height from the -Y component, and the width from the +X component, resulting in successful loading of the image.
Add autotest images for landscape and portrait HDR (Radiance RGBE) loader
BUGS: 433877
Due to various double vs float arithmetic,
some primaries could be rejected by Qt.
If necessary, we adjust the values so they
will be accepted by Qt.
Remove newline from the ends of error strings.
According to relicensecheck Brad is OK with changing LGPLv2 to LGPLv2+,
which is required to be compatible with the LGPL-2.1-or-later licensed
source files.
Since QImage does sanity checking for overflows and stuff wrt.
dimensions and depth, check for QImage::isNull() as early as possible to
see if there's some funky business going on.
Also tried to add some checks wherever we wrote to "raw" memory.
Unit tests pass, and tested converting some files from
https://samples.ffmpeg.org/image-samples/ to pngs, and that seemed to
work.

We added our own implementation of rand_r to make sure we use the same
as Gimp, and to make Windows work. But we need to actually use it
everywhere.

We now support up to and including version 11 of the XCF format, earlier
it only supported version 1 (from 1997, according to the XCF spec).
Biggest difference seems to be that they changed to 64bit for offsets
from version 11 and upwards, otherwise it's mostly just newer enum
values and theoretically major stuff that we don't really need to care
about to get a thumbnail (e. g. linear vs. perceptual RGB).
We still don't support all features, but now it handles that more
gracefully and should at least create thumbnails that are usable. It
should also be easier to update in the future if/when there comes new
versions.
Also added a test file created with the latest version of Gimp
(2.10.18).
