Re: search for better regtest comparison algorithm

[Han-Wen Nienhuys]

FWIW, I wrote a version of the comparison in Go that does the entire
comparison in-memory, without shelling out to any program. I did this
because it parallelized much better (ie. is faster), but it also means
you can easily test alternative algorithms.

See here: https://github.com/hanwen/lilypond-ci/blob/master/cmd/compare/main.go

Given the example you cite, maybe calculating optical flow would let
you detect and filter general motion of objects between two frames,
but from a quick look, it seems involved.
