A possibility is to surround the objects that you want to outline with a very slightly
larger, 
transparent version of itself. That object is set to rgbt 1 pigment. The trick is to
use 
fade_distance <small value>, fade_color rgb 0 and fade_power 999. The fade_distance
must be very 
close, but larger, to the size difference, or thickness of the "shell".
Getting everything OK is prety tricky, as you can go from a nearly invisible shell to
an opaque one 
with some very small changes.
I've tried it and it CAN work at least in some cases. Almost impossible to set up when
the object 
have any reflection.
