[vtkusers] Snycing interactors: interactor styles

[S, Navneeth (GE, Research)]

Hi Gerrick,

I think you have 2 options for syncing interactors:

1. The rather obvious one is to have 2 viewports in the same window that
share an interactor. 
But since your application has 2 windows by design. I guess this is
ruled out.

2. The other option is to create a tree/graph datastructure wherein you
maintain the parent-child relationship of the windows. Subsequently you
will need to have a callback that intercepts the Update events of the
renderer. You will then have to iterate through all the "children" of
the window and update their interactors to reflect the events in the
"parent".

This is off the top of my head. Pl dig into the redraw mechanism of the
interactor to verify this suggestion.
