Function cavalier_contours::polyline::internal::pline_intersects::find_intersects

pub fn find_intersects<P, O, T>(
    pline1: &P,
    pline2: &O,
    options: &FindIntersectsOptions<'_, T>

Find all intersects between two polylines.

In the case of overlapping intersects point1 is always closest to the start of the second segment (start_index2) and point2 furthest from the start of the second segment.

In the case of two intersects on one segment the intersects will be added as two PlineBasicIntersect in the order of distance from the start of the second segment.

In the case of an intersect at the very start of a polyline segment the vertex index of the start of that segment is recorded (unless the polyline is open and the intersect is at the very end of the polyline, then the second to last vertex index is used to maintain that it represents the start of a polyline segment).
