I already have the view set to 360x180 degrees.  It's not a simple
clipping either; the zenith image is clipped at some pitch, let me
guess about 70 degrees, but the images in the top row are not clipped,
and actually extend above the remaining visible portion of the zenith
image.  I suspect that the same thing is happening in nona, but I
can't tell because the remaining zenith is masked out.  I suppose I
could stitch as a multi-layer tiff and find out for sure...
