Polygon .Invert followed by .ContainsPoint panic #68

Closed jamespwilliams closed 4 years ago

jamespwilliams commented 4 years ago

Calling .Invert on a polygon and then calling .ContainsPoint causes a panic (at least, when initiated using PolygonFromLoops with a list of loops containing a single RegularLoop, I haven't tested other ways of initiating polygons).

I imagine this could quite likely be the same bug as #69.
