Found the problem.  Gradient as backgropund color needs to be treated 
differently from other colors.  In the Styles DSL this is done correctly, need 
to do it the same way in the shapes DSL.

In the Shape DSL there is now a error marker produced that says: "Using a 
gradient as background is not supported inside the shape DSL. Please use the 
style DSL for this."
