random low-fi visual effect idea: manual "interlacing" as motion blur (only draw odd scanlines on odd frames, even scanlines on even frames)

@eniko That's... actually pretty related to why interlacing is a thing in the first place.

Detail is less perceptible on moving objects, so it saves signal/work by sacrificing detail on moving objects while still keeping detail in things that aren't moving.

But, same concept applies to things like temporal AA, checkerboard rendering, etc.
