Utils

General :
- Added Dependencies : LibProERead needs to link with LibCreoViewRead
- Convergent bodies containing mesh and geometry with shared edges are introduced. A new surface Dtk_MeshSurface with type DTK_TYPE_MESH_SURFACE may exist now. This surface has no parametrisation , no nurbs conversion use Dtk_MeshSurface::GetMesh() to access geometry. We can currently find this kind of mixed bodies in files created into PARASOLID kernel environnement (Unigraphics, SolidEdge, JT, Parasolid, and SolidWorks).
- Added methods Dtk_Node::NodeHasMeshSurfaces() and Dtk_Body::HasMeshSurface() to detect mixed bodies with mesh and geometry
- Added method Dtk_Info::GetFlexibleFlag() to detect Flexible assembly - this flag is present on Dtk_Component type InstanceComponentType
- Fixed the function GetTransparentRatio of Dtk_LightMap (used by Dtk_RenderInfos). Now returns 0 for opaque elements, and 1 for fully transparent ones.
Tessellation :
- Added support of Convergent bodies containing mesh and geometry
