Hm, not sure. We can ask in this list: How does your camera do it? I'll need
to check with mine.
I'd assume that for files a (RAW) and b (JPEG) to form a pair,
- the same basename, only different suffixes, when downloading from the
camera, is sufficient
- the exact same creation date is necessary, but not sufficient if there are
other pictures with the same date+time
- same value in one of some metadata fields implemented as a UUID or click
counter is sufficient (see DMetadata::getImageUuid for potential candidates,
but the intention there is different)
