[vtkusers] FLTK and VTK on VC++

[Sean McInerney]

Hi Hassan,

Your main function does not seem to require FLTK at all. You have VTK's
standard interactor handling the event loop and never create any FLTK
widgets or start the FLTK event loop. I suggest testing what you have
without FLTK and later looking to available VTK - FLTK examples as
guides when it comes time to add a GUI.
