[Paraview] PImageData and vtkGhostLevels

[Charles Law]

Roland,

Ghost levels are needed for images when they are processed by filters that 
do not know their input is an image (vtkDataSet API).

The error message indicates that the ghost levels are not being generated 
correctly, or that they are not being updated for the new frame.  This 
check keeps filters from looking past the end of an array and crashing 
paraview.

Charles.
