Class for rendering a markups node.
This class can display a markups node in the scene. It plays a similar role to vtkWidgetRepresentation, but it is simplified and specialized for optimal use in Slicer. It state is stored in the associated MRML display node to avoid extra synchronization mechanisms. The representation only observes MRML node changes, it does not directly process any interaction events directly (interaction events are processed by vtkMRMLAbstractWidget, which then modifies MRML nodes).
This class (and subclasses) are a type of vtkProp; meaning that they can be associated with a vtkRenderer end embedded in a scene like any other vtkActor.

Methods to make this class behave as a vtkProp. They are repeated here (from the vtkProp superclass) as a reminder to the widget implementor. Failure to implement these methods properly may result in the representation not appearing in the scene (i.e., not implementing the Render() methods properly) or leaking graphics resources (i.e., not implementing ReleaseGraphicsResources() properly).

The widget representation can set this data member to true to indicate that it needs to be re-rendered. If the rendering request is processed then the flag is cleared.

Controls whether the widget should always appear on top of other actors in the scene. (In effect, this will disable OpenGL Depth buffer tests while rendering the widget). Default is to set it to false.

Specify tolerance for performing pick operations of points. For display renderers it is defined in pixels. The specified value is scaled with ScreenScaleFactor. For VR renderer it is defined in millimeters. The specified value is scaled with WorldToPhysicalScale.

Set the renderer in which the representations draws itself. Typically the renderer is set by the associated widget. Use the widget's SetCurrentRenderer() method in most cases; otherwise there is a risk of inconsistent behavior as events and drawing may be performed in different viewports. WARNING: The renderer is NOT reference counted by the representation, in order to avoid reference loops. Be sure that the representation lifetime does not extend beyond the renderer lifetime.

UpdateFromMRML() - update the widget from its state stored in MRML. if event is non-zero then a specific update (faster, smaller scope) is performed instead of a full update.
