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.
Gets the tangent of the path at the point.

If you want to orient something in the direction of the path, gsk.path_point.PathPoint.getRotation may be more convenient to use.
