Uh, clipped_by leaves a hole in the object and makes the wall infinitely
thin... since the cutting plane is normal to the viewing rays (orthographic
projection) I won't see a thing. I hoped bounded_by would work, by using it
"improperly" so the results are unpredictable, but it didn't. I'll go the
hard way (it works).
