Description

I forgot to adjust the infill density for these patterns when using multiline infill (sorry).
I realized this while watching this video:
https://www.youtube.com/watch?v=2FI39LruBdo&t=3s
I'm correcting it in this pull request to maintain consistency with the behavior of the other patterns.
It is important to ensure that the density multiplied by the number of lines does not exceed 100% to avoid excessive overlap. I have noticed that if the product exceeds 100%, Orca crashes (with lightning infill).
I also added this line in Filllightning:
e5ae18f55a/src/libslic3r/Fill/FillLightning.cpp (L23)
It is used to trim fill lines against perimeter and avoid artifacts when using multiline.
Update: Added GUI corrections , and deleted unnecessary variable by @ianalexis .
