Detailed Description

Geometry adapter for polygonal shape. This is a 'private' class of 'Surface' geometry. DO NOT USE IT DIRECTLY!

The Surface geometry stores individual polygons in space subdivision structure. But the SDS class is able to store only shapes (not geometries). Therefore the _Surface class merges properties of both parrent classes together.
