Thanks for the link Hans.  That's exactly what I was looking for.  I think I 
figured out the issue I was having.  In the DisplacementMapFilter constructor, 
you have to assign color channels for it to displace along x and y, and I was 
setting the displacement map to a black and white gradient.  When I created a 
red/green gradient, it worked.

Unfortunately, I can't download the zip source on that page.  :-/
