pub fn segment_triangle_find_local_separating_edge_twoway(
    segment1: &Segment,
    triangle2: &Triangle,
    pos12: &Isometry<f64>,
) -> (f64, Vector<f64>)

Finds the best separating edge between a segment and a triangle.

All combinations of edges from the segment and the triangle are taken into account.
