When searching for duplicate polygons, also check the reverse
  orientation.

* TEveGeoShape, TEveGeoShapeProjected, TEvePolygonSetProjected,
  TEveGeoShapeExtract:
  Introduce new flag 'Bool_t fMiniOutline' that instructs the renderer
  to minimize the shape outline.

  This still needs to be implemented for TEveGeoShape and
  TEvePolygonSetProjected.

* TEvePolygonSetProjectedGL:
  When mini-outline is requested, remove the inner lines.
