[vtkusers] Update 4.4 to 5.0 problem!

[de Boer Ingo]

Hi,

I have a problem with a class written by David Pont to solve
a problem concering the LookUpTable color interpolation.

Now, I have updated VTK from 4.4 to 5.0.1 an have some trouble
with it. I get the following error:

ERROR: In .\vtkExecutive.cxx, line 783
vtkStreamingDemandDrivenPipeline (01D6CBA8):
UpdateData invoked during another request.
Returning failure to algorithm vtkLookupTableToTexture(01D6C4A0).

Any hints on this ?
I guess I have to modify the class itself to make it work again,
but I haven't a clue where to start. There is nothing in the wiki
how to upgrade classes form 4.4 to 5.0. The webside search didn't
bring any clues either.

greets
  Ingo
