Clipping issue: Rendered triangle due to a makevalid producing invalid polygon.

[gdey]

Sometimes the makevalid function will create a polygon with a cutout that is not completely surrounded by the main ring. This results in a triangle artifact being rendered.

Here is a sample, this is on natural earth dataset. http://localhost:8080/?debug=true#5/51.391/10.159

GID of polygon: 62

Here is a location where is more contained. You can see the bad make valid as well. http://localhost:8080/?debug=true#6/53.939/10.077
