[vtkusers] Save vtkChartXY to PNG

[Jakub Poła]

Thank you for your help Jothy. This filter is working but I have to 
create renderWindow and call at least once Render() method to obtain 
proper output data from vtkWindowToImageFilter. I would like to omit 
render window and go directly from vtkChartXY to PNG ( Let  assume that 
there is no X11 support on the machine where program will work), but I 
suppose that it is not possible easily.
