[Paraview] Branding: Active element w/o pipeline browser

[Eric E. Monson]

Hey,

I've finally started taking a closer look at the new ParaView  
"Branding" (off of Utkarsh's git repository), and first of all I'd  
like to say that you have done an amazing job so far! This is going to  
make it so much easier to create custom-built PV-based applications.

I was looking at the Clone2 CustomApplication example  
(paraview_revised_2 app) which has a lot of standard PV, but doesn't  
include the pipeline browser. This is interesting to me because I  
think there will be cases when my users will want as simple an  
interface as possible, so I was wondering whether one function of the  
Pipeline Browser could be reproduced in another way:

If there is only a single data set loaded, with a linear pipeline,  
then the most recently applied filter/data is shown in the Object  
Inspector, and it's easy to change display parameters. If there are  
multiple data sets loaded, each with some filters applied, then  
without a Pipeline Browser there is no way to switch back and forth  
between the two currently displayed representations (if that is the  
right term) to change their display parameters, or add new filters to  
their branch of the pipeline.

Is there some natural way of adding another selection mode or tool  
that would let you click on an object in the 3D render view and it  
would make that representation (pipeline element) the active one, just  
like you can by clicking on an element in the Pipeline Browser?

Thanks again for all the nice work,
-Eric
