[vtkusers] vtkScalarsToColorsPainter in vtkDefaultPainter

[clinton at elemtech.com]

Hi,

I'm playing with a chain of painters to render multiblock data (with hundreds 
of blocks).. and in the documentation for vtkDefaultPainter, I see that is 
sets up the chain like this:
vtkScalarsToColorsPainter --> vtkClipPlanesPainter --> 
vtkDisplayListPainter --> vtkCompositePainter --> 
vtkCoincidentTopologyResolutionPainter --> vtkLightingPainter --> 
vtkRepresentationPainter --> <delegate>

If I move the vtkScalarsToColorsPainter to after vtkDisplayListPainter the 
rendering, for this case of multiblock data I was trying, was significantly 
faster.  It appears the speed is only because of avoiding the overhead of 
calling vtkScalarsToColorsPainter.

Is there a reason for that order?  Or am I free to change the order in my 
code?

Thanks,
Clint
