The gsk:path-point structure 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 instance, use the gsk:path-closest-point, gsk:path-start-point, gsk:path-end-point or gsk:path-measure-point functions.

Note that gsk:path-point instances are meant to be stack-allocated, and do not 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 instance is used.
