* Allow to modify/create EXIF 2.3 ASCII tags
Make `tag_is_ascii` aware of the EXIF 2.3 ASCII tags that are
available since libexif 0.6.22.
See: https://github.com/kleisauke/net-vips/issues/167
* Fix CI
* quick proposal
warn on startup if untrusted operations might run
use vips_block_untrusted_set() to block untrusted operations, set an env
var or make a file to stop the warning
* mark fits, nifti and svg as untrusted
* remove the annoying "untrusted" warning message
better to warn on the download page
leave vips_block_untrusted_set() since it's obviously useful
* separate UNTRUSTED and BLOCKED
* typos
* add VIPS_BLOCK_UNTRUSTED env var
* move BLOCK_UNTRUSTED after plugin load
obviously, ooops
* add a test, disable *magick
although *magick is fuzzed, it's probably safer to disable it in
untrusted environments
* mark some more operations as untrusted
* LSan: remove GLib suppression
* LSan: disable the fast unwinder to get full stacktraces
* Move ASan/UBSan fuzzer options to CI configuration
* LSan: remove EOLed python2.7 suppression
* LSan: remove libstdc++ suppression
* LSan: add libx265 to suppression file
* Try to reproduce small memleak
* Try a possible patch
* Skip test if `im_benchmark` is not available
* CI: upgrade Clang version to 13
* CI: correct job names
* Meson: increase the timeout for tests
* README.md: correct Meson invocation
- Remove unused libgif-dev dependency from CI.
- Remove no longer relevant comment from testsuite.
- Use yes/no instead of boolean values in configure.ac.
Instead of a simple fail/don't-fail boolean switch, add fail-on, an enum which sets the sensitivity of loaders to errors.
There's a new sensitivity level which tries to detect truncated images, but ignores other types of error.
* Add jpeg restart_interval option.
This allows saving a jpeg with MCU restarts.
* Fix code style. Add description of restart_interval.
* Add a basic test based on output length.
* Update main change log.
* fic gtk-doc typenames in cgif
* fix flatten clipping
flatten could produce out of range values if max_alpha was less than
the limit of the numeric range of the format

Provides control over the maximum number of colours in the output
image palette, making the API more closely match that of pngsave.
Lowering the bitdepth to 7 (from the default value of 8), which
halves the maximum number of colours from 255 to 127, typically
reduces encoding time by ~20%.
* Simplify CI workflow
* CI: upgrade Ubuntu's Clang version to 12
* CI: upgrade macOS runner to version 11 (Big Sur)
* CI: temporarily disable the M1 runner
* CI: output test suite log upon failure
* CI: avoid brew update/upgrade steps
Since it may take a long time.
* CI: all jobs are supposed to succeed
* Fix test_descriptors.c failure after f8c2a36
Use a RANDOM image to create many crops from one source.
Some programs, like indesign, only work with premultiplied alpha in TIFF. To
make TIFFs which are compatible with these programs, we'll need an extra
TIFF save flag (perhaps premultiply?) to premultiply alpha and save as
EXTRASAMPLE_ASSOCALPHA.
