Process camera manipulation events.
This widget does not have a visible representation, only translates and processes camera manipulation (rotate, translate, etc.) events. It is implemented as a widget instead of an interactor style so that mouse and keyboard interaction events can be dynamically remapped to camera manipulation actions and to process all kinds of interaction events (camera manipulation, markups manipulation, ...) in a similar way.
