Yes indeed, that does work-- and it didn't occur to me, duh.
I originally tried a bunch of permutations of the 'right' vector itself-- among
other things-- because I could not easily figure out what the basis of the
distortion was (until I decided to use the gradient x+y idea as a tester.) Then
it became obvious.
I need to remember that image_height and image_width are actual *values* that
can be used in a scene. ;-)
