getTangent
Gets the tangent of the path at the point.
Note that certain points on a path may not have a single tangent, such as sharp turns. At such points, there are two tangents -- the direction of the path going into the point, and the direction coming out of it. The @direction argument lets you choose which one to get.
If the path is just a single point (e.g. a circle with radius zero), then @tangent is set to 0, 0.
If you want to orient something in the direction of the path, method@Gsk.PathPoint.get_rotation may be more convenient to use.
