Class for holding 2D geometry.
This class will hold 2D geometry consisting of a number of closed
contours. A polygon can contain holes and islands, as well as
intersecting contours.
polygons. Each polygon can contain holes and islands. Both polygons,
holes and island contours may intersect each other.
We can store sanitized vs. unsanitized polygons. Sanitized polygons
will have opposite winding order for holes and is guaranteed to not
have intersecting geometry. The winding order will be counter-clockwise
