Host-neutral motion-vector analysis and interpolation filters.
This crate contains the reusable core of vapoursynth-zoomvtools without any
VapourSynth dependency. Host integrations pass borrowed plane slices through
[FrameView] and [FramePlanesMut], persist vector metadata with
[MVAnalysisData], and call filter structs such as [Super], [Analyse],
[Compensate], and [Degrain].
