If you're gonna do optional lines then it'll only look correct
when viewed from one direction. This means you can apply the
standard cheat to solve the problem with cutoff cylinders on
concave edges. Push all the edge cylinders toward the camera
by half a radius or so. (Similar to glPolygonOffset) You could
probably make a EdgeLineOffset macro so you only have to change
one line when you change the camera. Or perhaps you can tie
it to the camera macros.
Perhaps if you move the optional lines away from the camera,
you'd only see the ones that peek out from around the edges of
the model. But then they'd be partially obscured.
