Move scalar bar GL2PS special case handler from PV to VTK.

This patch moves the special handler code for scalar bars from paraview
into VTK. The code was originally in PV as the PVScalarBar differed
significantly from vtkScalarBar, but now that they share more of their
implementations VTK can handle the export.
