Spectrum editor now uses a private scene and region-rendition to display the spectrum. To change the graphic on the spectrum editor, the rendition-graphic displaying the glyph must know that something in the graphics object has changed. We have a callback function setup for that but at this moment this callback function only returns 1 or 0, instead it should tell the rendition-graphic that something has been changed.
