/**
* @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.
*
* @sa
* vtkAreaPicker
