[vtkusers] _cdecl error in pickcells.cxx example

[shaun selha]

Hello Everybody,

  I am trying to compile the pickcells.cxx example and I keep getting an
error on the line:

   iren->SetEndPickMethod(PickCells, (void *)iren);

  which reads:

  'SetEndPickMethod':cannot convert parameter 1 from 'void(void *)' to 
   'void(_cdecl*)(void*)'

  If anybody has come across this before or could be of assistance please
let me know

Thanks,
Shaun
