[Bf-funboard] Food for thought: lower subsurf subdiv value during transform?

This sounds really good. I'm using subsurfs a lot and this might be 
another step towards what I call "realtime-workflow" (don't I just love 

And while we're at it: if subsurf-levels can be changed on the fly, why 
not link this behaviour to something else like, ...hmmm... , distance 
from camera? Wouldn't that be level-of-detail on subsurf-objects?

If implemented on the rendering-stage as well this would be really cool 
for animatics (preview-renderings) which I have to do quite often.

More flexibility on subsurfs might lead to many interesting 
improvements, keep it up!
