Details:

The EdgeAlpha and/or EdgeLighting properties do not seem to have an effect on
Fill() or patch() plot objects.  Example code: 

f1=figure(1) 
clf; 
hold on 
grid on 
h=fill([90,210,210,90],[-.8,-.8,.8,.8]); 
set(h,'FaceColor',[0,0,0]); 
set(h,'FaceAlpha',0.25); 
set(h,'EdgeColor','none'); 
set(h,'EdgeAlpha',0); 
set(h,'EdgeLighting','none'); 
axis([50,250]); 

What I expect is a totally flat, featureless transparent rectangle.

What I get is a transparant rectangle but nothing I try gets rid of the edge
of the rectangle.   I have tried various values for EdgeAlpha without success.
 Same for EdgeLighting.
