experiment with removing shutdown from atexit ( #2439 )
...
remove shutdown from atexit
Because atexit() can be called at almost any point during process termination,
including after worker threads have been force-quit, we can't use it for
cleanup.
New policy: use vips_shutdown() explicitly if you need to clean up,
though it's optional. Only use atexit() for leak checking.

raise the PNG text chunk limit

Raise the PNG text chunk limit to 50, since it seems some real images
have a text chunk per line of exif data.

* Ensure UBSan exits with a non-zero code on error
* Avoid misaligned member access in mosaic_fuzzer
* Add missing VIPS_CLIP in scRGB2sRGB/scRGB2BW
* Fix UBSan error in flatten
By using saturated casts for the int types (copied from vips_cast).
* CI: ensure fuzzer log is printed on error
* Avoid UB in heifload
* Revert flatten change
I could no longer reproduce this with clang 12 locally.
* Indentation fixes [skip ci]

gifsave: expose bitdepth property ( #2429 )
...
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%.

arrayjoin signalling minimise also frees memory
...
By making the sequential line cache non-persistent, and only minimising
when the read point is well past the image.
On large arrayjoin operations, this saves many GB of memory.

minimise arrayjoin inputs during processing
...
arrayjoin with a sequential pipeline will now minimise inputs when they
are no longer being used. This drops the number of open file handles
needed to construct large arrays.
Sadly, memory savings are minimal.
