/**
* @class vtkInteractorStyleTrackballCamera
* @brief interactive manipulation of the camera
*
* vtkInteractorStyleTrackballCamera allows the user to interactively
* manipulate (rotate, pan, etc.) the camera, the viewpoint of the scene. In
* trackball interaction, the magnitude of the mouse motion is proportional
* to the camera motion associated with a particular mouse binding. For
* example, small left-button motions cause small changes in the rotation of
* the camera around its focal point. For a 3-button mouse, the left button
* is for rotation, the right button for zooming, the middle button for
* panning, and ctrl + left button for spinning. (With fewer mouse buttons,
* ctrl + shift + left button is for zooming, and shift + left button is for
* panning.)
