Now that the righthandedness has gone into the PlotWindow objects, making slices and projections of isolated disk galaxy simulations yields the y-projection having a vertically oriented disk as seen here in an image generated by Mike Butler:

I suppose we could modify the ProjectionPlot framework to allow a keyword to specify the x-axis and y-axis vectors, but I was just trying to make equivalent projections using the OffAxisProjectionPlot object since that allows for one to explicitly specify a north_vector.  Unfortunately, I'm finding some inconsistencies between the ProjectionPlot (on-axis) images and the OffAxisProjectionPlot images (specifying vectors to be on-axis).

This simple script demonstrates what I'm talking about:

Running this script yields 4 images:

As you can see, the off_axis_proj is using significantly different limits than the on_axis_proj, which makes me think it isn't doing a true line integral, but I haven't investigated this closely.  While the weighted projections are better, they still have slight differences in their limits.  Is this expected and I'm just messing something up here, or is this a true bug?
