I thought about this - so we have two options here: 1. adding it to `SnapshotOptions` 2. adding it to every function which I do not like as this would be a huge breaking change ## Summary This pull request introduces a new feature to the `SnapshotOptions` struct in the `egui_kittest` crate, allowing users to specify a permissible percentage of pixel differences (`diff_percentage`) before a snapshot comparison is considered a failure. This feature provides more flexibility in handling minor visual discrepancies during snapshot testing. ### Additions to `SnapshotOptions`: * Added a new field `diff_percentage` of type `Option<f64>` to the `SnapshotOptions` struct. This field allows users to define a tolerance for pixel differences, with a default value of `None` (interpreted as 0% tolerance). * Updated the `Default` implementation of `SnapshotOptions` to initialize `diff_percentage` to `None`. ### Integration into snapshot comparison logic: * Updated the `try_image_snapshot_options` function to handle the new `diff_percentage` field. If a `diff_percentage` is specified, the function calculates the percentage of differing pixels and allows the snapshot to pass if the difference is within the specified tolerance.
