[IGSTK-Developers] View refactoring- Camera control

Not exactly camera control, but related to the view classes:
The background color of a view should be controllable by the client  
of the class.
I see in igstkViewNew that there is a public method getRenderer().  
That would solve this. Will this stand? If not, I wish for a  
SetBacgrundColor() in igstkViewNew
