[vtkusers] MarchingCubes/ScalarRange Bug ?

	Using vtkMarchingCubes from VTK4.0 if I set the contour level at
say 593, then call GetScalarRange on the output, I get [592,593]. Because
of this, in my mapper with a custom LUT I need to set LUT values for both
592 and 593.  If I just set 593 with a value, about 1/3 of the cells
appear transparent. If I give LUT values for both 592 and 593 the output
is as expected. Any reason for this?  Thanks.
