I'm seeing issues with .pam, .pcx, and .wbmp files so far. They just don't open, and the first other image (a .gif in this instance) is opening in cosmic-viewer instead when I double click them.

Still finding sample files to test with for some of the other formats.

The .pam, .pcx, and .wbmp files I found don't work in EOG either, so I don't think they're an issue.

I did find two formats that work in EOG but not cosmic-viewer, but I don't think they're in the mime type list, so I'm not sure they're an issue. They are .avif and .tga files which I generated with GIMP. I can share them if needed, but apparently not in Github.

cosmic-viewer still has issues with high-res images, are we sure we want to set it as default?

Here's me trying to zoom in on a screenshot I just took:
