vscale orientation

[Dean Skuldt <skuldt mr radiology wisc edu>]

Hello, 

A vscale I have created is oriented so that the adjustment's value is
upper when the slider is at the bottom of the scale, and the adjustment's
value is lower when the slider is at the top of the scale.  How do I flip
it so that the upper is at the top and the lower is at the bottom?
Setting the scale's value position (TOP, BOTTOM, LEFT, RIGHT) has no
effect.  

Thanks, 

Dean
