// General offset_extrude and fillet_extrude. | |
// These use minkowski which can be incredibly slow and resource intensive, but should theoretically work on any 2d geometry. | |
// fillet_extrude is also much slower than offset_extrude, due to significantly more facets needed for rounded edges. | |
// There are some alternative methods which are much faster, | |
// ***BUT*** they have the limitation of only working for CONVEX children. | |
// chamfer_extrude (basically like offset_extrude): https://gist.github.com/thehans/072005c68e5fcef3394b8c08e37d1c35 |
