i think that (given that in principle mp produces stand alone ps code) 
it should start out with black; when embedding as eps or when used as 
xform in pdf thsi probably is automatically taken care of

it makes sense to let mp do that for you; there are a few places where 
context forces the defaultcolor; we can make it an opion in the mp topdf 
converter as well
