Hi all,

Has there been a change to the add_projection or add_thin_projection routines for unweighted projections?  I have some projection scripts from ~a month ago that are all off by like 20 orders of magnitude on the color bar limits for unweighted projections.  The only thing that makes sense to me is that yt is now dividing the line of sight integration by the depth of the projection.  So it is sum(f(i)*dl(i))/sum(dl(i)) instead of sum(f(i)*dl(i)).  Is that right?  I don't think it used to do that.  It's fine if that is now what it is doing, but I just want to make sure.  I'm a little confused.
