// This test covers the lighting flag on a vtkProperty object of an vtkActor.
// It draws a cone with lighting next to a cone with no lighting, next to a
// third cone with lighting again.
// 
// The command line arguments are:
// -I        => run in interactive mode; unless this is used, the program will
//              not allow interaction and exit
