classifyPointContainment Method

Returns 1, 2, or 3 based on whether point array is strongly inside, ambiguous, or strongly outside respectively.

• This has a peculiar expected use case as a very fast pre-filter for more precise clipping.
• The expected point set is for a polygon.
• Hence any clipping will eventually have to consider the lines between the points.
• This method looks for the special case of a single clip plane that has all the points outside.
• In this case the whole polygon must be outside.
• Note that this does not detect a polygon that is outside but "crosses a corner" -- it is mixed with respect to multiple planes.
