Requesting a shader global exposed to differentiate between rendering in the photo camera and stream camera.

I have some shader-driven animations on my avatar that don't look good in static photos, but look fine when captured in video using the stream camera. I'd like to degrade the animation for photos and not for video, but currently there's no way to do this, and I have to degrade it in all camera types.

(It would also be neat to be able to differentiate rendering in the photo cam's viewfinder versus rendering for the actual captured photo.)
