Re: shape thickness

Hi Bill

I tried that earlier and ran into a problem.  I am constantly
changing the data displayed by my application.  When I change
the data I removeAllReferences() from my display, reset the
data and re-add the references.  If I add a constant map in
addReference(), the second time I add the reference I get
an exception saying that I can't add the same constant map
twice.  But, if I don't add a constant map, the data is
displayed as though a constant map isn't there at all.

I looked through the visad/example code.  The closest
example creates a new display and then adds all the scalar
and constant maps.  I'd prefer not to create a new display
everytime I change the data.

How can I get around this?
