// .NAME vtkInteractorStyleTrackballCamera - interactive manipulation of the camera
// .SECTION Description
// 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.)
