This rewrite is more or less necessary for:
- colour-managed browser thumbnails,
- asynchronous image loading,
- turning fiv-io into a reusable library.
Little CMS has a fairly terrible API in this regard.
It works well for my Nikon.
Note that hot pixels can be eliminated in the camera itself,
when you run sensor cleaning immediately after a very long exposure
of darkness.
This makes use of our image processing capabilities in order to
turn arbitrary image files into normalized thumbnails,
upload them to a temporary host, and pass the resulting URI
to a search provider.
In future, fiv should ideally run the upload itself,
so that its status and any errors are obvious to the user,
as well as to get rid of the script's dependency on jq.
- Fix launching of subprocesses (missing gspawn helpers).
- Discard unused GSettings schemas.
- Make the program find its user guide.
- Bundle a somewhat suboptimal version of ExifTool.
Implement a process-local VFS to enable grouping together arbitrary
URIs passed via program arguments, DnD, or the file open dialog.
This VFS contains FivCollectionFile objects, which act as "simple"
proxies over arbitrary GFiles. Their true URIs may be retrieved
through the "standard::target-uri" attribute, in a similar way to
GVfs's "recent" and "trash" backends.
(The main reason we proxy rather than just hackishly return foreign
GFiles from the VFS is that loading them would switch the current
directory, and break iteration as a result.
We could also keep the collection outside of GVfs, but that would
result in considerable special-casing, and the author wouldn't gain
intimate knowledge of GIO.)
There is no perceived need to keep old collections when opening
new ones, so we simply change and reload the contents when needed.
Similarly, there is no intention to make the VFS writeable.
The process-locality of this and other URI schemes has proven to be
rather annoying when passing files to other applications,
however most of the resulting complexity appears to be essential
rather than accidental.
Note that the GTK+ file chooser widget is retarded, and doesn't
recognize URIs that lack the authority part in the location bar.
Now SIMD works on amd64, although the build remains questionable,
because it assumes that all of its compiler flags will work.
This way we lose an uncomfortable git submodule.
Also, add Meson subprojects to .gitignore.
There is no point in claiming speed, it turns out to be a strange focus
to have, considering the amount of available innovations to make.
The new name does not appear to be taken by anything important.
