Yes,  and a lot of us are lazy and very naughty and use:

right x*image_width/image_height


It's worth pointing out at this early stage that "x" is a reserved keyword,
shorthand for the cardinal x basis vector, <1, 0, 0>.

So after multiplying, you get: <image_width/image_height, 0, 0>

Maybe this will help explain better, or help to further confuse you...  :D
