[vtkusers] Turning Auto Rescaling Off on vtkActor2D

[Gerrick Bivins]

Hi Sarah,
How is your vtkScalarBarActor set up? At what point does it become
unreadable? Can you provide a screen cap of the problem. I'm using
vtkScalarBarActor w/o issues when resizing my window. 

Here is my setup:
        scalarbar = new vtkScalarBarActor();
        scalarbar.SetOrientationToHorizontal();
       
scalarbar.GetPositionCoordinate().SetCoordinateSystemToNormalizedViewport();
        scalarbar.GetPositionCoordinate().SetValue(.2,.05);
        
        scalarbar.SetWidth( 0.7 );
        scalarbar.SetHeight( 0.1 );
        scalarbar.SetPosition( 0.1, 0.01 );
        scalarbar.SetLabelFormat("%-#6.3f");
        scalarbar.GetTitleTextProperty().SetFontFamilyToArial();
        scalarbar.GetTitleTextProperty().SetFontSize( 12 );
        scalarbar.GetLabelTextProperty().SetFontFamilyToArial();
        scalarbar.GetLabelTextProperty().SetFontSize(10);
        scalarbar.GetLabelTextProperty().SetJustificationToCentered();

This keeps it placed at the bottom of my window with all of it's properties
(width,height,position) relative to the window.
