/**
A node that has methods to draw outlines or use indices of vertices to create navigation polygons.

There are two ways to create polygons. Either by using the $(D addOutline) method or using the $(D addPolygon) method.
Using $(D addOutline):
$(D code)
var polygon = NavigationPolygon.new()
var outline = PoolVector2Array($(D Vector2(0, 0), Vector2(0, 50), Vector2(50, 50), Vector2(50, 0)))
polygon.add_outline(outline)
polygon.make_polygons_from_outlines()
$NavigationPolygonInstance.navpoly = polygon
$(D /code)
Using $(D addPolygon) and indices of the vertices array.
$(D code)
var polygon = NavigationPolygon.new()
var vertices = PoolVector2Array($(D Vector2(0, 0), Vector2(0, 50), Vector2(50, 50), Vector2(50, 0)))
polygon.set_vertices(vertices)
var indices = PoolIntArray(0, 3, 1)
polygon.add_polygon(indices)
$NavigationPolygonInstance.navpoly = polygon
$(D /code)
