just did a successful test with a library implementing some algorithms for curve fitting (i.e. taking a bunch of points and trying fit nice beziers into them, which is e.g. used for smoothing lines).
initial tests look promising and will publish as soon as this has some form.
i just updated this pack to 2.0.0 to make it compatible with the current 5.3 previews (thanks to @verstecke for pointing out the incompatibility). furthermore it is now also not a prerelease any more so please install with
