Utils

Dtk_LayerFilterInfos :
- Add Method to get layer name using it's ID : Dtk_ErrorStatus Dtk_LayerInfosSet::GetLayerNameById( const Dtk_ID inLayerID, Dtk_string& outLayerName ) const;
Tessellation :
- We suppressed method tess_set_MinSize() this method is in conflict with the tessellation parameters values, it can change the precision of the mesh result, we prefer to suppress this option.
- Now we tesselate original surfaces (without approximation to nurbs), this increase the precision.
