org.geotools.renderer.lite.StreamingRenderer.paint()
Renders features based on the map layers and their styles as specified in the map context using setContext.
This version of the method assumes that the size of the output area and the transformation from coordinates to pixels are known. The latter determines the map scale. The viewport (the visible part of the map) will be calculated internally. @param graphics The graphics object to draw to. @param paintArea The size of the output area in output units (eg: pixels). @param worldToScreen A transform which converts World coordinates to Screen coordinates. @task Need to check if the Layer CoordinateSystem is different to theBoundingBox rendering CoordinateSystem and if so, then transform the coordinates. @deprecated Use paint(Graphics2D graphics, Rectangle paintArea,ReferencedEnvelope mapArea) or paint(Graphics2D graphics, Rectangle paintArea, ReferencedEnvelope mapArea, AffineTransform worldToScreen) instead.

      Map<Object, Object> rendererParams = new HashMap<Object, Object>();
      rendererParams.put(StreamingRenderer.OPTIMIZED_DATA_LOADING_KEY, true);
      // we use OGC scale for predictable conversion between pix/m scale and relative scale
      rendererParams.put(StreamingRenderer.SCALE_COMPUTATION_METHOD_KEY, StreamingRenderer.SCALE_OGC);
      renderer.setRendererHints(rendererParams);
      renderer.paint(graphics, mapContext.getViewport().getScreenArea(), mapContext.getViewport().getBounds());
