Note that gsk.path_point.PathPoint structs are meant to be stack-allocated,
and don't hold a reference to the path object they are obtained from.
It is the callers responsibility to keep a reference to the path
as long as the gsk.path_point.PathPoint is used.
gsk.path_point.PathPoint is an opaque type representing a point on a path.
It can be queried for properties of the path at that point, such as its tangent or its curvature.
To obtain a gsk.path_point.PathPoint, use gsk.path.Path.getClosestPoint, gsk.path.Path.getStartPoint, gsk.path.Path.getEndPoint or gsk.path_measure.PathMeasure.getPoint.
