Edge resolution is not too great a problem with stitching since you 
normally allow plenty of overlap of the images.  With my 8mm lens on 35mm I 
use 3 shots, so that's 195° overlap for a 360° panorama. 65° of the image 
is not used (but is useful for selecting control points to aligning/correct 
the images) I also shoot 2 vertical image (1 up, 1 down) so there's also 
plenty of overlap there as well.
