      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.
