public class PathPoint

`GskPathPoint` 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 `GskPathPoint`, use [method@Gsk.Path.get_closest_point], [method@Gsk.Path.get_start_point], [method@Gsk.Path.get_end_point] or [ method@Gsk.PathMeasure.get_point].

Note that `GskPathPoint` 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 `GskPathPoint` is used.

Methods:

public int compare (PathPoint point2)
Returns whether this is before or after point2.
public PathPoint copy ()
public bool equal (PathPoint point2)
Returns whether the two path points refer to the same location on all paths.
public void free ()
public float get_curvature (Path path, PathDirection direction, out unowned Point? center)
Calculates the curvature of the path at the point.
public float get_distance (PathMeasure measure)
Returns the distance from the beginning of the path to this.
public Point get_position (Path path)
Gets the position of the point.
public float get_rotation (Path path, PathDirection direction)
Gets the direction of the tangent at a given point.
public Vec2 get_tangent (Path path, PathDirection direction)
Gets the tangent of the path at the point.
