You could achieve it at the application level but it would be difficult and
would add significant complexity to how applications deal with rendering
images. This would entail using different transforms for different parts of
the image which would require adding addition logic to track what parts of
the image appear on what actual display device. At this point applications
like GIMP, CinePaint and the like make an assumption that the user will only
display images on a single physical display.
