Preview pictures for the preset packs the Cometfly app offers, so a pack's presets show their pictures as soon as it is downloaded.
Each release is one edition of the renderer, with one zip per pack, named after the pack and the commit of its
repository. Inside, every picture is <SHA-256 of the preset file>.avif, 384 px, and undrawable.txt lists the
presets that could not be drawn.
The presets are by their authors, from the projectM-visualizer preset repositories. These are pictures of what each one draws, not the presets themselves. If you made a preset and want its picture taken down, open an issue and it will be removed.
