> When a polygon have two consecutive points very close to each other but not
> numerically identical, we can get wrong results because planes defining that
> edge intersects somewhere else on the world. At that point the following
> check is evaluated to true:
> {code:java}
> if (edge.plane.evaluateIsZero(thePointX, thePointY, thePointZ) &&
> edge.startPlane.isWithin(thePointX, thePointY, thePointZ) &&
> edge.endPlane.isWithin(thePointX, thePointY, thePointZ)) {
> return false;
> }{code}
