Add a bunch of features

* stereo instancing
* outlines
* shadows (casting & receiving)
* unity fog
* blend modes
* wrapped lighting (generalized half lambertian)
  * diffuse & specular have independent knobs

Also:

* fix bug where shadow caster wouldn't clip in cutout mode.
* remove a bunch of unused params
* use ifex to minimize size of locked materials (more to be done
  probably)
* improve formatting
