Add instancing distance culling, scale deformation

* GPU instance distance culling now takes a min/max range
* Fold recovers ops from material, allowing state to persist across
  editor restarts
* Add scale node to vertex deformation framework
* Remove fold presets - dumb LLM idea, unused
* Drop more "undeform" code; unused, was for ray marching, which does
  not work well
* Fix reflection energy compensation; was using cloth math, which makes
  things too bright
