I got frustrated with the experience of reviewing image snapshot changes (from egui_kittest, thus the name) in my ide and on github, so I made something really cool:
Just run kitdiff in your terminal and it'll visualize all the diffs! You can use the 1, 2, 3 keys to switch between original, new, diff images. You can also generate diffs on the fly to play with different threshold options. Also, it's wicked quick!
