New issue 892: OffAxisProjection yields different results than OnAxisProjection

Cameron Hummels:

ProjectionPlot (on-axis) images and the OffAxisProjectionPlot images (specifying vectors to be on-axis) appear to yield different results:

This simple script demonstrates what I'm talking about:

Running this script yields 4 images:

The weighted images are basically the same for both on and off-axis, but the unweighted images are significantly different.  Suggestion from @ngoldbaum that perhaps the projection conversion was not being applied correction in the non-weighted off-axis projection.  Wanted to make an issue of this problem before I forget about it.
