// .NAME vtkInteractorStyleRubberBandPick - Like TrackBallCamera, but this can pick props underneath a rubber band selection rectangle.
//
// .SECTION Description
// 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.
//
// .SECTION See Also
// vtkAreaPicker
