Wrapper for TGeoShape with absolute positioning and color attributes allowing display of extracted TGeoShape's (without an active TGeoManager) and simplified geometries (needed for non-linear projections).
TGeoCompositeShapes and TGeoAssemblies are supported.
If fNSegments data-member is < 2 (0 by default), the default number of segments is used for tesselation and special GL objects are instantiated for selected shapes (spheres, tubes). If fNSegments is > 2, it gets forwarded to geo-manager and this tesselation detail is used when creating the buffer passed to GL.
