[vtkusers] Disable warning about "does not support stereo"

[Alex Malyushytskyy]

Sorry I do not know of the way how to disable specific warning,
but this warning comes from  void vtkRenderWindow::SetStereoRender(int
stereo)

it would be called from
vtkInteractorStyle::OnChar()


You may subclass vtkInteractorStyle you use -
(for example vtkInteractorStyleTrackballCamera ), override
  virtual void OnChar();

Something like below will work:

//--------------------------------------------------------------------------
void vtkInteractorStyleRubberBand::OnChar()
{
   switch (this->Interactor->GetKeyCode())
   {
     case '3':
         vtkObject::GlobalWarningDisplayOff();
         this->Superclass::OnChar();
         vtkObject::GlobalWarningDisplayOn();
         return;
   }
    this->Superclass::OnChar();
}


Basically you are not guaranteed that other warnings which may happen are
enabled, but you limit time warnings are disabled.
