Unless of course 120 wide by 160 high was intended.

Nothing wrong with using the exact same numbers taken from the resolution,
ie. right 320/340. Reducing fractions isn't always something you might want
to be taking time to do for uncommon ones.  ;-)  In fact, remember, POV-Ray
3.5 will do this with the new keywords like so: right
image_width/image_height. Then there isn't even any confusion over which is
which.
