SOme combinations of high bitdepth images with low bitdepth PNG save could
produce incorrect images, for example saving a 16-bit fourier image as 1-bit.
Having a different colorspace and chroma subsampling just because the
source image happens to be an even or odd number of pixels is surprising
and hard to debug, so let's remove it.
We were avoiding /0 by testing for alpha==0, however, this will still
allow very small values of alpha to generate +/- Inf. Instead, check for
abs(alpha)<epsilon.
Fixes some artifacts after unpremul.
We were minimising at the end of threadpool_run, but this was being
called for each sinkscreen render pass, so we were throwing away the
display cache.
Instead, minimise after sink, sink_memory and sink_disc.
To disable DoS limits for JPEG loading. Adding API on a stable branch is
bad, but this fixes a regression, so I think it's necessary,
unfortunately.

* Allow to modify/create EXIF GPS* tags
Make `tag_is_ascii` aware of the EXIF GPS* ASCII tags that are
available since libexif 0.6.23.
See: https://github.com/lovell/sharp/issues/2767
* Add tests
* Remove `glib-mkenums` autotools templates and generated files
Meson uses the `enumtypes.c.in` and `enumtypes.h.in` in
`libvips/include/vips` and doesn't use the pre-generated
files.
* Remove man files for no longer existing tools
+ update the `meson.build`.
* Remove Autotools section in `.gitignore`
* Remove `po/messages` left-over
* Remove `g-ir-scanner` entry point
No longer needed by Meson.
* Remove `glib-genmarshal` generated files
Meson doesn't use these pre-generated files.
* Remove Autotools specific Git attributes
* Remove no longer existing tools in `.gitignore`
* Remove Make specific things in `.gitignore`
* Rename COPYING to LICENSE
* Remove no longer needed `.gitignore` sections
Meson only supports out-of-tree builds. This assumes that the
build directory is ignored.
* Remove no longer needed `.editorconfig` sections
The `*_class_intern_init` functions have already been patched within
wasm-vips to include the missing `class_data` member, so this adapter
function was not needed.
* Avoid writing the full path in enumtypes.h
Helps reproducible builds, as build paths can vary between builds.
* Use g_intern_static_string() for enum/flags type names
We are emitting a static string, so use that shortcut function to
intern it, which will save one allocation.
* Use g_once_init_enter/leave to register enum/flags type names
This is the more modern way, and ensures thread-safety.
1. Convert MULTIBAND uint/short/etc. as we convert uint8 images. They
are probably just uint8 that have been cast up in format.
2. Don't check that the image interpretation is a supported colourspace
before calling vips_colourspace() ... we want to fail with an error
if it can't be converted, not silently accept the image.
Loaders which supported random access would not set the seq flag even if
seq mode was requested.
This would make operations like shrinkv to not run in seq mode, causing
massive cache thrashing.
