[metapost] logo10 P and S

[Laurent Méhats]

Hello,

I came accross hardly discernible strokes that affect the smoothness of
the contour lines of the P and S glyphs of the MetaPost logo, returned by
the glyph operator. My gess is that they shouln't be there but I have no
idea where they come from: the font, the glyph operator, a misuse (I'm
always in a mess when it comes to fonts) ?

beginfig(0)
path pth[];
idx:=0;
for tkn within glyph "P" of "logo10":
  pth[idx]:=pathpart tkn;
  idx:=idx+1;
endfor
drawarrow pth[0];
drawarrow pth[1];
show subpath (5, 6) of pth[1];
draw subpath (5, 6) of pth[1] withcolor red;
draw fullcircle scaled 25 shifted point 5.5 of pth[1];
endfig;

beginfig(1)
path pth;
for tkn within glyph "S" of "logo10":
  pth:=pathpart tkn;
endfor
drawarrow pth;
show subpath (7, 8) of pth;
draw subpath (7, 8) of pth withcolor red;
draw fullcircle scaled 25 shifted point 7.5 of pth;
endfig;

end
