[NTG-context] metafun color broken?

13 Jun 2006

      I used to draw in transparent color in MetaFun with:

    newinternal tfill_mode; tfill_mode := 1;	% transparency mode for  
inside
    newinternal tfill_fact;	tfill_fact := 1;	% transparency factor  
for inside
    def withFillColor = withcolor transparent(tfill_mode, tfill_fact,  
fillcolor_) enddef;
    fill somepath withFillColor;

Suddenly (since the june update I guess) this fails.
Because

    fill somepath withcolor fillcolor_;

is still working I wonder if something has done to this transparency  
business.
If there was a change, why? It brings me trouble.
