[Bug] Specific Polygons That Won't Union #78
Description
Hi,
I have two polygons:
geo1 = Geometry::Polygon.new(Geometry::Point[1691, 957], Geometry::Point[1677, 1175], Geometry::Point[1635, 1173], Geometry::Point[1649, 951])
geo2 = Geometry::Polygon.new(Geometry::Point[1690, 1033], Geometry::Point[1687, 1139], Geometry::Point[1670, 1138], Geometry::Point[1673, 1030])
When I call geo1.union(geo2) it throws an error:
Error:
TestBox#test_broken_box:
NoMethodError: undefined method `first' for nil:NilClass
/home/deus-ex/.gem/ruby/2.7.1/gems/geometry-6.5/lib/geometry/polyline.rb:143:in `close!'
/home/deus-ex/.gem/ruby/2.7.1/gems/geometry-6.5/lib/geometry/polygon.rb:32:in `initialize'

/home/deus-ex/code/title_reader/test/test_box.rb:147:in `test_broken_box'
However, if I call geo2.union(geo1) it works fine. It also works if I change the first point in geo2 to Geometry::Point[1695, 1033]. I don't know enough about geometry to debug this further.
Thanks!
