// .NAME vtkOldStyleCallbackCommand - supports legacy function callbacks for VTK
// .SECTION Description
// vtkOldStyleCallbackCommand is a callback that supports the legacy callback
// methods found in VTK. For example, the legacy method
// vtkProcessObject::SetStartMethod() is actually invoked using the
// command/observer design pattern of VTK, and the vtkOldStyleCallbackCommand
// is used to provide the legacy functionality. The callback function should
// have the form void func(void *clientdata), where clientdata is special data
// that should is associated with this instance of vtkCallbackCommand.
//
// .SECTION Caveats
// This is legacy glue. Please do not use; it will be eventually eliminated.
// .SECTION See Also
