// .NAME vtkSMExtentDomain - int range domain based on data set extent
// .SECTION Description
// vtkSMExtentDomain is a subclass of vtkSMIntRangeDomain. In its Update
// method, it determines the minimum and maximum extent in each dimension of
// the structured data set with which it is associated. It requires a
// vtkSMSourceProxy to do this.
// .SECTION See Also
// vtkSMIntRangeDomain

  // Description:
  // A vtkSMProperty is often defined with a default value in the
  // XML itself. However, many times, the default value must be determined
  // at run time. To facilitate this, domains can override this method
  // to compute and set the default value for the property.
  // Note that unlike the compile-time default values, the
  // application must explicitly call this method to initialize the
  // property.
