Hi,

I get different results when I compile the following file using mkii and 
mkiv. See the attached pdf output. I am using (I know, I need to update)

mpost -v = MetaPost 1.005 (Web2C 7.5.5)
context --version = 2008.06.22 17:38


\setupcolors [state=start]
\starttext

   z.1 = (-1cm, 0) ;
   z.2 = ( 1cm, 0) ;
   z.3 = (0, -1cm) ;
   z.4 = (0,  1cm) ;

   path p[] ;

   p.1 := z.1 -- z.2 ;
   p.2 := z.3 -- z.4 ;

   draw p.1 ;

   draw p.2 withpen pencircle scaled 3bp withcolor white ;
   draw p.2 ;
