Subject: Don't bother saving n2 percentage
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=6fd86ab6b7784e11f67c879b51c37c6e0011416f;p=ext%2Fsubsurface.git

Don't bother saving n2 percentage

It's all calculated anyway, and for the same reason we don't bother even
parsing it at load time, we really shouldn't bother saving it either.

The only thing you can do with that value is "check if the percentages
add up to 100%", and so what?
