// This test exercises whether display attributes can be overridden for certain
// datasets in a composite dataset.
//
// The command line arguments are:
// -I        => run in interactive mode; unless this is used, the program will
//              not allow interaction and exit
// In interactive mode, you can press the 'n' or 'N' key to cycle visibility of
// the individual shapes.
