Hi Richard -
How about making one ribbon thicker than the other, so there's no ambiguity
about which is on top? You can set cartoon_rect_length and
cartoon_rect_width for individual objects...
In my experience, though, ambiguity about which surface is on top just
produces mottled surfaces - one triangle of one color next to a triangle of
the other color.
Could you post a link to a picture of the artifacts?
