[vtkusers] vtkFlRenderWindowInteractor.

[Kalpathi Subramanian]

I am trying to port some of my old code to Mac OSX Lion(64bit). This 
includes
the bridge code between vtk and fltk.  I am having a hard time getting this
to work on the Mac OSX. In particular I have tracked it down to the 
Iniitialize()
call of the renderwindow interactor.  It seems like I have to do this 
initialization
after the fl windows  show() call (else it crashes), but the 
Initialize() doesnt
create the window within the window. My latest code snippet simply doesnt
create the vtk canvas at all. Any mouse inputs to the window causes 
error messages
(Timer start failed)

Anyone has an example that is working that they can share - I can then 
pattern my
code on that.

I have ensured that vtk (5.8) and fltk (1.3) independently work fine -- 
tested
examples, so those  have no issues. Its combining the two together thats 
been
frustrating.

Thanks.
