`(lines-closer CAM-ID DIST)`
  Draw lines (including edges) closer to the camera than polygons by DIST / 10^5 of the Z-buffer range. DIST = 3.0 by default. If DIST is too small, a line lying on a surface may be dotted or invisible, depending on the viewpoint. If DIST is too large, lines may appear in front of surfaces that they actually lie behind. Good values for DIST vary with the scene, viewpoint, and distance between near and far clipping planes. This feature is a kludge, but can be helpful.
