Tessellation

Miscellaneous
- The following functions/methods are now deprecated:
  - Dtk_Frame::CreateGeometries(Dtk_tab< Geometric_set_select_entity *>& outGeoms) const
  - Dtk_Text::CreateFrameAsGeometry(Dtk_tab<Geometric_set_select_entity*> &outGeoms) const
  - Dtk_CompositeText::CreateFrameAsGeometry(Dtk_tab<Geometric_set_select_entity*> &outGeoms) const
  - Dtk_Leader::ConvertToGeom( Geometric_set_select_entity **outGeomsArray )
  - Dtk_Dimension::ConvertExtensionLineToGeometries(const Dtk_Size_t &inExtLinePos,Geometric_set_select_entity **&outGeomsArray, Dtk_Size_t &outGeomsNum) const
  - Geometric_set_select_entity * Dtk_Dimension::GetExtraGeometry(const Dtk_Size_t &inPos) const
  - Dtk_ToleranceSpecification::Explode(Dtk_CompositeText &outCompositeText,Dtk_tab<Geometric_set_select_entity*> &outGeoms)
  - Dtk_ToleranceSpecificationContainer::Explode(Dtk_CompositeText &outCompositeText,Dtk_tab<Geometric_set_select_entity*> &outGeoms)
  - Dtk_Symbol::AddGeometricalElement( Geometric_set_select_entity * inGeomElt )
  - Geometric_set_select_entity * Dtk_Symbol::GetGeometricalElement( const Dtk_Size_t & inPos ) const
  - Dtk_View::AddGeometricalElement(Geometric_set_select_entity * inGeomElt)
  - Dtk_View::AddGeometricalElements(const Dtk_tab<Geometric_set_select_entity*> &inGeomEltArray)
  - Dtk_View::GetNumGeometricalElements()
  - Geometric_set_select_entity * Dtk_View::GetGeometricalElement( const Dtk_Size_t& inPos ) const
- In consequence they will raise a warning each time they will be used.
