Submitted by user lihop; MIT; 2021-07-06

Ported from pixelmatch (https://github.com/mapbox/pixelmatch), this is a small, simple and slow GDScript pixel-level image comparison library.

- Allows you to count how many pixels differ between two images and can generate a new image with customizable colors to highlight these differences.

- Has a tunable threshold property and the ability detect and ignore anti-aliased pixels.
