Function intersects

intersects(a: vec2.Vec2, b: vec2.Vec2, c: vec2.Vec2, d: vec2.Vec2): boolean
Tests whether the two closed segments a-b and c-d intersect. Collinear (overlapping) segments are treated as non-intersecting; touching at an endpoint counts as an intersection.
Parameters
- a: vec2.Vec2
  first endpoint of the first segment
- b: vec2.Vec2
  second endpoint of the first segment
- c: vec2.Vec2
  first endpoint of the second segment
- d: vec2.Vec2
  second endpoint of the second segment
Returns boolean
true if the segments intersect
