/**
* @class vtkParallelCoordinatesInteractorStyle
* @brief interactive manipulation of the camera specialized for parallel coordinates
*
* vtkParallelCoordinatesInteractorStyle allows the user to interactively manipulate
* (rotate, pan, zoom etc.) the camera.
* Several events are overloaded from its superclass
* vtkInteractorStyleTrackballCamera, hence the mouse bindings are different.
* (The bindings keep the camera's view plane normal perpendicular to the x-y plane.)
* In summary, the mouse events are as follows:
* + Left Mouse button triggers window level events
* + CTRL Left Mouse spins the camera around its view plane normal
* + SHIFT Left Mouse pans the camera
* + CTRL SHIFT Left Mouse dollys (a positional zoom) the camera
* + Middle mouse button pans the camera
* + Right mouse button dollys the camera.
* + SHIFT Right Mouse triggers pick events
*
* Note that the renderer's actors are not moved; instead the camera is moved.
