/// The {{Outline}} method allows the caller to produce a geometry with an equivalent fill to the input geometry, with the following additional properties: The output geometry contains no transverse intersections; that is, segments may touch, but they never cross.The outermost figures in the output geometry are all oriented counterclockwise. The output geometry is fill-mode invariant; that is, the fill of the geometry does not depend on the choice of the fill mode. For more information about the fill mode, see <see cref="Vortice.Direct2D1.FillMode"/>.Additionally, the {{Outline}} method can be useful in removing redundant portions of said geometries to simplify complex geometries. It can also be useful in combination with <see cref="ID2D1GeometryGroup"/> to create unions among several geometries simultaneously.
