vtkOrientedGlyphContourRepresentation lost ability to stay on top.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
With the move to the OpenGL2 backend it seems that widgets are unable to call OpenGL. Because of this change in behavior the feature AlwaysOnTop for ContourRepresentation is now a no-op for both the OpenGL1 and OpenGL2 backend.
