[Bf-vfx] Lens workflow diagram in Blender

[Francesco Paglia]

Since we are naturally going for a complete workflow that is node related I
don't see usefull the shader at rendertime but... When we don't use any kind
of real life plate we would still use the distortion  to feel our picture
more real. in that case would be cool to store somewhere some preset of
distortion data to use it.

should be done in comp - coding resources will be better spent on
implementing reliable overscan rendering with proper implementation of
separated display windows/data windows throughout the pipeline.
