[vtkusers] Color invertion for volume Data

[circass]

i thought the same thing until i saw my program crashes :)
i dont know the reason but when i use imageshiftscale and after that set the
slice number of my viewer, it crashes. i think the reason can be the range
or something like that.

these are my old codes.

	inverter->SetShift(-255);
	inverter->SetScale(-1);

with this code i could make the color inversion. i think these lines must be
changed properly for 3d.
