SectionMarker Class
A Marker associated with a SectionDrawingLocationState, displayed as a canvas decoration at the location of the section. Clicking on the marker toggles display of the section graphics. Mousing over the marker produces a toolbar with additional interactions.
see HyperModelingDecorator for a Decorator capable of displaying section markers for each section drawing location.
see SectionMarkerHandler to customize the marker interactions.
