/**
 * @class   vtkInteractorStyleRubberBandPick
 * @brief   Like TrackBallCamera, but this can pick props underneath a rubber band selection
 * rectangle.
 *
 *
 * This interactor style allows the user to draw a rectangle in the render
 * window by hitting 'r' and then using the left mouse button.
 * When the mouse button is released, the attached picker operates on the pixel
 * in the center of the selection rectangle. If the picker happens to be a
 * vtkAreaPicker it will operate on the entire selection rectangle.
 * When the 'p' key is hit the above pick operation occurs on a 1x1 rectangle.
 * In other respects it behaves the same as its parent class.
 *
