/**
* @class vtkRenderedAreaPicker
* @brief Uses graphics hardware to picks props behind
* a selection rectangle on a viewport.
*
*
* Like vtkAreaPicker, this class picks all props within a selection area
* on the screen. The difference is in implementation. This class uses
* graphics hardware to perform the test where the other uses software
* bounding box/frustum intersection testing.
*
* This picker is more conservative than vtkAreaPicker. It will reject
* some objects that pass the bounding box test of vtkAreaPicker. This
* will happen, for instance, when picking through a corner of the bounding
* box when the data set does not have any visible geometry in that corner.
