Subject: [PATCH] Use non-deprecated methods to access OpenCascade
 Triangulation elements

The Triangles() and Nodes() accessors have been deprecated in favor
of the Triangle(index) and Node(index) methods, available since OCC 7.2.0,
i.e. for over 5 years.

The Nodes() method has been removed with OCC 7.6.0, and Triangles() is
also slated for removal (currently). Use the non-deprecated methods,
and also fix the types of the index variables to Standard_Integer.
