Comment:

 Unfortunately a fix that involves an expensive area calculation, but we
 only need to do that if we have interior rings: VML renders polygons with
 sub-paths that have no area incorrectly when the stroke-width is greater
 than 1. The solution is to not close sub-paths that have a zero area.

 Added tests, tests pass in IE8, example polygon renders fine. Thanks for
 any review.
