another option would be to ignore transparent objects on the last
trace level, so the ray ends up intersecting with some object which
is actually visible in the scene. Not sure about opaque reflective
objects, remove those and the ray may end up in some part of the
scene with which light isn't actually exchanged at all. But I think
most artefacts with max_trace_level occur with glass/water anyway.
