[metapost] Clipped svg output

[Lutz Haseloff]

Please have a look at this:

outputformat := "svg";
outputtemplate := "%j-%c.%{outputformat}";
for i = 1 upto 10 :
beginfig(i)
pickup pencircle scaled i ;
draw fullcircle scaled 20 ;
endfig;
endfor;
for i = 11 upto 20 :
beginfig(i)
fill fullcircle scaled i ;
endfig;
endfor;
end

No problems with even numbers.
Even without pen.

Greetings Lutz
