Fix off-by-one error in ComputeBounds() for vtkPlotPoints
Fix off-by-one error in ComputeBounds() for vtkPlotPoints

This fixes an off-by-one error in ComputeBounds() for vtkPlotPoints
when the input data has bad points (NaN's/Inf's). The bad points
index variable (i) was being incremented before looking up the next
bad point causing the range to be too large. In that case a NaN value
could be used in the calculation causing the function to return
(NaN - NaN) as the bounds for the data.

This fixes the pv.SLACTools test in ParaView.
