This function is optional. If supplied, it will be called during editing and rendering when the viewer window needs updating or a process parameter has changed.
Any graphics drawn in the Open GL RGB Plane during editing should be performed within this function. OpenGL projections are set up for projection of the full/master raster resolution coordinate space on the screen.
