Even after SetTextScaleModeToNone(), SetFontSize (200) doesn't seem to
have any affect on the text size:

  vtkSmartPointer<vtkAxesActor> axes = vtkSmartPointer<vtkAxesActor>::New();
  axes->GetYAxisCaptionActor2D ()->GetTextActor()->SetTextScaleModeToNone();

  vtkSmartPointer<vtkTransform> transform =
      vtkSmartPointer<vtkTransform>::New();
  transform->Translate(1.0, 0.0, 0.0);

  // The axes are positioned with a user transform
  axes->SetUserTransform(transform);

  axes->GetXAxisCaptionActor2D()->GetCaptionTextProperty()->SetColor(1,0,0);
  axes->SetXAxisLabelText("hello");
  axes->GetXAxisCaptionActor2D ()->GetCaptionTextProperty()->SetFontSize (200);

  renderer->AddActor(axes);

The "ScaleMode" idea is a good one - rather than specify the actual
font size it would be nice to specify the font size with respect to
the axis arrow heads or something like that.

Any further thoughts on any way to control the font size?

Thanks,
