// .NAME vtkPVHardwareSelector - vtkHardwareSelector subclass with paraview
// sepecific logic to avoid recapturing buffers unless needed.
// .SECTION Description
// vtkHardwareSelector is subclass of vtkHardwareSelector that adds logic to
// reuse the captured buffers as much as possible. Thus avoiding repeated
// selection-rendering of repeated selections or picking.
// This class does not know, however, when the cached buffers are invalid.
// External logic must explicitly calls InvalidateCachedSelection() to ensure
// that the cache is not reused.
