[BUG] polylines with only 1 point

[paul-gdy]

Hi,

I talked about it in this commit. However as I'm not a regular github user I think it will be easier to comment here.

I understand that path.addPolygon is better than path.lineTo (comment).
But I notice that path.addPolygon needs at least 2 points. In my case, I have to display lines with only 1 point.

Thus would it be possible to be sure the line is drawn even if it has only 1 point.

Just for clarity, a line needs 2 points as well, it's just that the original had a bug in it, and added a duplicate 1st point by mistake (no matter how long the line). addPolygon just randomly happened to avoid that...(I'm not necessarily a fan of having a 2 point polygon, but I'll stay out of that one :D).

Is there a particular reason you can't add a 2nd identical point to your list ? That would be the correct thing to do.

It sounds good for me, thank you !
