New raw thumbnailer

I have resurrected my camera old raw thumbnailer so that I can browse directories full of of camera raw images in Nautilus. This is version 47.0.1, because GNOME 47 is out.

Like the old one, it uses libopenraw to extract the previews from the raw files.

But, it now supports more raw formats, and if needed will render the raw image to generate a preview, like it has to for my old Ricoh GR Digital II images (the one from 2007). This leverage libopenraw 0.4.0 (still in alpha stage) that has been rewritten in Rust.

Sadly to get is in the hands of users the only good solution is a distribution package. At the time of writing there is none, but I put together smething that allowed me to build a package for Fedora 40 to install on my big rig.

If you feel like it you can download the source code from GNOME, and the repository is on GNOME gitlab.

This is how it looks with Nautilus 46 with a bunch of images from my old Olympus E-P1:
