projectM visualization presets shipped with Guayadeque.

Source: https://github.com/projectM-visualizer/presets-cream-of-the-crop
(a curated subset of 50 presets, ~600 KB; the full pack is ~10000 presets /
156 MB and is not vendored here).

MilkDrop presets were, in almost all cases, not released under any specific
license. Each preset author holds the copyright on their creation; since they
were freely released and used in countless packages over two decades, the
projectM team treats them as public domain. If you are a preset author and
don't want your work shipped here, contact us and it will be removed.

Users can add more presets (any .milk files) through the Visualizer
preferences page (preset folder) — the playlist picks up every preset found
recursively in that folder.
