Title: Improve Polygon robustness

We had a czml file converted from kml that had polygons with all the same points. When duplicate points were removed, the polygon had no points, and an exception was thrown.

This pull requests changes `Polygon` to handle - and by handle, I mean not render in - situations where removing duplicate points results in not enough points to form a polygon (< 3).

This is minor enough that I did not update CHANGES.md.
