        void paint​(Graphics2D graphics,
           Rectangle paintArea,
           AffineTransform transform)
        Render features based on the org.geotools.map.LayerList, bounding box and org.geotools.styling.Style specified in the context.
        Parameters:
        graphics - The graphics handler to draw to.
        paintArea - The bounds of the output area in output units (usually pixels). The upper left corner is (0,0) in most cases. However, a different value is allowed if some widget area must be preserved, for example a margin on the left and top size for painting a graduation.
        transform - A transform which converts "World coordinates" to output coordinates. This transform will be concatenated to the graphics transform (as of graphics.transform(transform)) before the rendering take place.
