-- Really our goal is to figure out if moving the end of the
-- path crosses over the anchor, which feels like a point/triangle
-- collision
-- We also want to pick the anchor that the ray sweeps over first, not
-- the closest one.
-- Maybe we should
-- (1) sort by angle difference from the original line
-- (2) ignore cases where the angle is not between the two lines
-- (3) ignore cases where the created point is further from the original point
-- than the _intended_ one would be
