[Fwd: Re: [NTG-context] metaobj and transparent colors with \MPcolor]

input metaobj;
beginfig(1)
 fill fullcircle scaled 1cm withcolor red;
  color t; t:=(1,1,0);
  %setObjectDefaultOption("Box")("fillcolor")(t);
  newBox.test("");
  Obj(test).c=origin;
  drawObj(test);
endfig;
end.
Your color is not transparent, so it will work as expected: no white
box.
???

The example demonstrated that it *IS* drawn white box in the background
of every metaobj object. Exactly as you mentioned.

But I had a second look into mpobj.mp and probably find out the white
box tiger. Comment line 750:
   unfill BpathObj(n);
I am sure this hack will cause some unpleasant side-effects (e.g. with
shaded boxes) but in some limited situations...
