[Yt-dev] Change in behavior of smoothed covering grids and ghost zones

Hi all,
Dave and I were chatting a couple weeks ago, and it became clear to me
that yt currently does something incorrectly with ghost zones and
smoothed covering grids. As it stands, in the smoothed covering grids
and the vertex centered data, the fields that are interpolated between
points are logged, then interpolated, then 10^values is returned.
This is not how Enzo does it, and I think yt should change too.
This may change some user-facing behavior, so I wanted to clear it
with everyone here first. This would change primarily the generation
of ghost zones, which are used for some finite stencils and for the
volume rendering. (However, I have been unable in my tests to see any
changes in the volume rendering.)
What do you all think?
-Matt
