The resetfig() macro from metafun clears "_op_" and "background".
I don't know why, but there''' be a reason for it, I am sure ;-)

There almost certainly is an 'official' way to add some statements to
the beginning of each figure, but, in any case, it works if you store
your settings in extra_beginfig:

   \startMPinclusions
   extra_beginfig := "drawoptions(withcolor green)";
   \stopMPinclusions
