Hi, 

This work isn't for Gooseberry only, at least I wasn't targeting
Gooseberry when I started working on it. It was merged in the Gooseberry
branch for a few reasons: 

- it's somewhat usable 
- it improves cache sizes 
- it _can_ result in faster rendering (this highly depends on the VDB
tree topology) 
- coincidence (this could have been done a year ago, or after
Gooseberry) 
- the Gooseberry team is using Linux machines, and it compiles fine on
Linux (with a few quirks and quarks dependency wise) 

So yeah, it's not Gooseberry only, and any change made regarding the VDB
work in the gooseberry branch shall be ported to the openvdb branch. 

Cheers, 
Kévin
