manage contention for cursors and other resources
The vtkObserverMediator is a helper class that manages requests for cursor changes from multiple interactor observers (e.g. widgets). It keeps a list of widgets (and their priorities) and their current requests for cursor shape. It then satisfies requests based on widget priority and the relative importance of the request (e.g., a lower priority widget requesting a particular cursor shape will overrule a higher priority widget requesting a default shape).
