Add support for silhouette edges
Should be able to reuse much of the shadow edges logic to tag lines with their adjacent face normals, then only render silhouette edges
Similar to Mesh.shadow, might be able to have
Mesh.silhouette : Mesh coordinates a -> Silhouette coordinates
and then Scene3d.silhouette, Scene3d.withSilhouette etc.
Possibly useful: use trick described in http://www.terathon.com/gdc07_lengyel.pdf to adjust depth calculation, instead of using actual polygon offset
