vtkSwtComponent.java:68 uses unreferenced symbol from parent class
vtkSwtComponent uses the renderWindow from its parent class vtkAbstractComponent. However, the called method in line 68 renderWindow.SetFrameBlitModeToBlitToCurrent() cannot be resolved. Reason being the renderWindow in vtkAbstractComponent is initialized as vtkRenderWindow. However, only the subclass of vtkRenderWindow vtkOpenGLRenderWindow has this method. So either the abstraction to vtkRenderWindow in vtkAbstractComponent or the use of renderWindow.SetFrameBlitModeToBlitToCurrent() in vtkSwtComponent is wrong. Please fix this.
