[vtkusers] VolumePro-board & cropping

[Lisa Avila]

Hello Steffen,

I suspect you are not really cropping the volume. If you are using the 
cropping planes in the mapper - this will not improve your performance 
because the whole volume is still sent across. If you are using a 
vtkImageClip then be sure to do ClipDataOn.
