Function centroid

centroid(
    out: vec2.Vec2,
    a: readonly [number, number],
    b: readonly [number, number],
    c: readonly [number, number],
): vec2.Vec2
Computes the centroid of the triangle (a, b, c).
Parameters
- out: vec2.Vec2
  the output vector to store the result.
- a: readonly [number, number]
  the first vertex of the triangle.
- b: readonly [number, number]
  the second vertex of the triangle.
- c: readonly [number, number]
  the third vertex of the triangle.
Returns vec2.Vec2
out.
