/* Three points are a counter-clockwise turn if ccw > 0, clockwise if
* ccw < 0, and collinear if ccw = 0 because ccw is a determinant that
* gives the signed area of the triangle formed by p1, p2 and this point.
* In other words it is the 2D cross product of p1-p2 and p1-this, i.e.
* z-component of their 3D cross product.
* We return double because it must be big enough to hold 2*max(|coordinate|)^2
