Actually, ShowImage does lossless rotation, in fact, it doesn't rotate 
the image itself, but only writes an attribute. Every app that knows 
this attribute must then rotate the image for you before showing it to 
you.
A lossless rotation as in JPEG is obviously something that would need 
support in the Translation Kit; I would move that into the R2 realm.
