Polygons should require a minimum of 3 vertices

[smeijer]

A polygon should have at least 3 vertices to be a valid polygon. A polygon with 2 vertices should be drawn as a line, as 2 points don't make a valid ring.

Point: 1 vertex
Line: 2 vertices
Polyline: 2 or more vertices
Polygon 3 or more vertices

And yet, we check here for a minimum of 2. Can we fix that? Optionally make it configurable to have backward compatibility?

edit, or actually 4. If you also count the closing vertex. A polygon is always circular, where the last vertex equals the first.

Yes, will get fixed. Thanks for reporting

Hm this should already be the case. Have you tried it? On the demo page and in my tests, it only finishes the polygon if there are 3 or more vertices.

The code doesn't check for a minimum of 2. It checks for a maximum of 2 and if true does NOT finish the shape.

Let me know if you encounter problems
