* Write temp images to private tmp directory (Linux)
The directory is in /tmp with 700 permissions.
* Reduce temp image file permissions in Linux
Set temporary image file permissions to read/write for the user only.
* Use private tmp directory for temp images in MacOS
* Use private tmp directory for temp images Windows
* Use GLib to create temporary directories
* Reuse temp directory if possible
* dng gainmap support, #6379
* dng GainMap: control sensitivity of checkbox, #6379
* dng GainMap: partial paste
* dng GainMap: moved isGainMapSupported() from dcraw.h to dcraw.cc
* RawImageSource::applyDngGainMap: small speedup
* Change GUI to separate gainmap from other flat-field; also reorder checkbox

* Use mtime as fallback timestamp for files without EXIF data
As suggested in #6449, with date-based sorting it can be useful to have
at least *some* sort of time-relevant information for EXIF-less files,
to prevent them from falling back to getting sorted alphabetically all
the time.
This commit simply defaults the file timestamp to the file's mtime as
returned by g_stat. For annoying reasons, it doesn't suffice to merely
forward the timestamp to the FileData structs - we also need to keep
track of it inside FilesData to cover the case of a file with 0 frames
in it.
* Add DateTime to Thumbnail
Putting it here facilitate easier sorting without having to re-construct
the DateTime on every comparison.
To simplify things moving forwards, use the Glib::DateTime struct right
away. This struct also contains timezone information, but we don't
currently care about timezone - so just use the local timezone as the
best approximation. (Nothing currently depends on getting the timezone
right, anyway)
In addition to the above, this commit also changes the logic to allow
generating datetime strings even for files with missing EXIF (which
makes sense as a result of the previous commit allowing the use of mtime
instead).
* Implement file sorting in thumbnail view
For simplicity, I decided to only implement the attributes that I could
verily easily reach from the existing metadata exported by Thumbnail.
Ideally, I would also like to be able to sort by "last modified" but I'm
not sure of the best way to reach this from this place in the code.
It's worth pointing out that, with the current implementation, the list
will not dynamically re-sort itself until you re-select the sorting
method - even if you make changes to the files that would otherwise
affect the sorting (e.g. changing the rank while sorting by rank). One
might even call this a feature, not a bug, since it prevents thumbnails
from moving around while you're trying to re-label them. You can always
re-select "sort by ..." from the context menu to force a re-sort.

With some versions of Glib/Glibmm library on MacOS, Glib::KeyFile "load_from_file" function does not raise a Glib::Error but another exception. This causes cached data not saved on disk (and thumbnails not displayed in explorer). Adds robustness testing if file is present first before calling the function
- When loading an image, raw histogram data were incorrectly not set (but provided)
- Fixes incorrect curve scaling in raw histogram mode (was incorrectly scaled using luma and chroma data)
Fixes:
- Fixes GUI issue on Windows (GDI handles limit reached)
- Fixes an incorrect icon name in Perspective tool
- Adds robustness RTScalable::loadSurfaceFromIcon function
Changes:
- Remove RTPixbuf use in directory browser to use native GTK mechanism
- Replace RTPixbuf by RTSurface for thumbnail icons
- Remove now useless RTPixbuf class
Fixes:
- Elaborate RTSurface width / height based on the type
