As shown in the commit, this is exactly what it contains. There was a redundant and seemingly meaningless `.clone()` in `about.rs`, which I removed. Was it because the function signature of `Image::new()` was different in older versions of egui? Co-authored-by: EtherealPsyche <EtherealPsyche@users.noreply.github.com>
