Description

This ports the Scattered Rectilinear Infill option from Superslicer originally implemented in this commit.

Also closes / addresses #876

This infill pattern lends itself greatly for diffusing and scattering light due to its randomness both in alignment and horizontal density per layer.

Additional Info

There is a good amount of additional information available in this reddit thread and this thingiverse post from the same author

I have tried using the rotation metalanguage over this infill pattern (with 360~100%), but after some printed tests (that I naively discarded..) I found that specifically the centerpoint of the sliced model was often darker due to the metalanguage only rotating and not also translating. Example image (taken and modified from here):

Images

Here are some images of a model I created with different exposures. You can't see it that great, so the upper resources are probably better, but you can't really see any pattern which is the purpose of this infill.

Thoughts

Please let me know if I should adjust anything, I am also not at all attached to the icon, I just tried matching the current style somewhat.
