[vtkusers] vtkDistanceWidget - changing the bound shape

[Sid Murthy]

Thanks Carlos -

   That did work although I noticed the size of handle doesn't scale
properly as the user zooms out (it gets bigger). I ended up setting handle
size to a small amount (essentially making it not visible to the user and
just having a straight line with the measurement label).

I am positioning this widget programmatically with
SetPoint1WorldPosition/SetPoint2WorldPosition and don't want users to
change it's position (although I can't get the widgets to be "locked" in
place to avoid this).
