For the x/y offset to be correct (center the video), you have to add 0.5
to x/y for every 1 you remove from w/h.  Since every other time we go
through the while() loop, w/h will be even, checking if w/h is
divisible by 2, and adding one then, seemed to be the best way to adjust
x/y.

Does that answer your question?
