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.

Defaults to no subsampling when Q>90 for consistency with jpegsave.
Deprecate VipsForeignJpegSubsample enum, replace with more generic
VipsForeignSubsample.
Fix two bugs:
- clip in casts from int32 and uint32 could overflow -- do these as gint64 now
- clip in casts from float to int could overflow since float32 can't
represent the full range of int32 without losing precision -- do these
as double
And add some more tests.
