[metapost] Problem with clip and svg output

[Pétiard François]

Hello

With that file:


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
prologues:=3;
outputtemplate:="%j_%c.%{outputformat}";

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%% EPS %%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
outputformat:="eps";
u:=1bp;
beginfig(1);
for i=-12 upto 2:
   draw u*(2*i,-10)--u*(2*i+20,10);
endfor;
clip currentpicture to fullcircle scaled(20u);
draw fullcircle scaled(20u);
endfig;

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%% SVG %%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
outputformat:="svg";
u:=5bp;
beginfig(1);
for i=-12 upto 2:
   draw u*(2*i,-10)--u*(2*i+20,10);
endfor;
clip currentpicture to fullcircle scaled(20u);
draw fullcircle scaled(20u);
endfig;

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%% PNG %%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
outputformat:="png";
u:=10bp;
outputformatoptions:="format=rgba antialias=best";
beginfig(1);
for i=-12 upto 2:
   draw u*(2*i,-10)--u*(2*i+20,10);
endfor;
clip currentpicture to fullcircle scaled(20u);
draw fullcircle scaled(20u);
endfig;

end;
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


the eps and the png output are correct but not the svg output (the clip 
is rectangular, not round).

Is it normal (limitation of svg, for example) ?

Best regards
