Wave — https://github.com/jtrivedi/Wave
Pinned upstream: 27b7e1d2d42b8a4f56d9e84213910b0441c8b810
MIT license; copyright 2022 Janum Trivedi.
Sources/Wave contains upstream Swift sources, without Documentation.docc.
Motch uses Spring and CGFloat.updateValue directly, with a main-thread macOS
CADisplayLink and fixed integration substeps in Sources/NotchMotion. Wave's
legacy CVDisplayLink animation controller is not invoked by Motch.
