[Bf-cycles] Agus3D Patches

[Nate Wiebe]

Since the next release has become postponed, there was some talk about
possibly getting a few new features in. Specifically a couple patches
from Agus3D [Mist and PerBSDF displacement]. Last I heard, PerBSDF was
ready to go, and mist is still being worked on.

Any chance of getting either or both in trunk before the next release?

Mist I can see as being committed for the next release, but PerBSDF
disp. seems ready to me. I personally had a insignificant slowdown
(Less than 0.5%) and others had similar results. Patch is here:

I understand it if neither make it, but both seems like it would
greatly benefit what we can currently do in Cycles and would be nice
for Mango ;).
