// .NAME vtkSMViewProxyInteractorHelper - helper class that make it easier to
// hook vtkRenderWindowInteractor and vtkSMViewProxy.
// .SECTION Description
// vtkSMViewProxyInteractorHelper is a helper class designed to make it easier
// to hook up vtkRenderWindowInteractor to call methods on a vtkSMViewProxy (or
// subclass). It's primarily designed to work with vtkSMRenderViewProxy (and
// subclasses), but it should work with other types of views too.
//
// To use this helper, the view typically creates a instance for itself as register
// itself (using vtkSMViewProxyInteractorHelper::SetViewProxy) and then calls
// vtkSMViewProxyInteractorHelper::SetupInteractor(). This method will initialize
// the interactor (potentially changing some ivars on the interactor to avoid
// automatic rendering, using vtkRenderWindowInteractor::EnableRenderOff(), etc.)
// and setup event observer to monitor interaction.
//
// vtkSMViewProxyInteractorHelper only using vtkSMViewProxy::StillRender() and
// vtkSMViewProxy::InteractiveRender() APIs directly. However several properties can
// be optionally present on the view proxy to dictate this class' behaviour. These
// are as follows:
//
// \li \c NonInteractiveRenderDelay :- when present provides time in seconds to
// delay the StillRender() call after user interaction has ended i.e.
// vtkRenderWindowInteractor fires the vtkCommand::EndInteractionEvent. If
// missing, or less than 0.01, the view will immediately render.
//
// \li \c EnableRenderOnInteraction :- when present provides a flag whether the interactor
// should trigger the render calls (either StillRender or InteractiveRender) as
// a consequence of interaction. If missing, we treat EnableRender as ON.
