// .NAME vtkImageOrthoPlanes - Connect three vtkImagePlaneWidgets together
// .SECTION Description
// vtkImageOrthoPlanes is an event observer class that listens to the
// events from three vtkImagePlaneWidgets and keeps their orientations
// and scales synchronized.
// .SECTION See Also
// vtkImagePlaneWidget
// .SECTION Thanks
// Thanks to Atamai Inc. for developing and contributing this class.
