Summary: PolarPlot Foreground Alpha

Initial Comment:
The setting of foreground alpha has effect only on
gridlines not on chart polygon. Please change the
drawing order in the PolarPlot.draw() to following:

if (this.renderer != null) {
   Shape originalClip = g2.getClip();
   Composite originalComposite = g2.getComposite();

   drawGridlines(g2, dataArea, this.getAngleTicks(),
      state.getTicks());
   g2.clip(dataArea);           
   g2.setComposite(AlphaComposite.getInstance(
        AlphaComposite.SRC_OVER,
getForegroundAlpha()));            
   // draw...
   render(g2, dataArea, info);
          
   g2.setClip(originalClip);
   g2.setComposite(originalComposite);
}

AND remove the setting of alpha
 
g2.setComposite(
     AlphaComposite.getInstance(AlphaComposite.SRC_OVER,
         0.5f)
);

by DefaultPolarItemRenderer.drawSeries()
