5.0.2.1 - 12 January 2013
* Update: Clipper library updated to version 5.0.2. The Area algorithm has been updated and is faster.
  'CheckInputs' parameter of the OffsetPolygons function has been renamed 'AutoFix'.
* Added: ClipperLib.Clean(), which removes too near vertices to avoid micro-self-intersection-artifacts when offsetting.
* Added: ClipperLib.Lighten(), which reduces count of vertices using perpendicular distance reduction algorithm.
* Added: ClipperLib.Clone(), which make true clone of polygons.
Several updates to the Main Demo:
* Added: Clean, Simplify, Lighten buttons

* Added: Polygon Output Formats (Clipper, Plain, SVG)
* Update: Polygon Explorer: Also multipolygon is clickable (on Points column)
