It isn't painfully obvious on large images, but when I was working on
"Showbots" (IRTC entry from last year), I was rendering some scenes at
40x30 (to accomplish the digital censoring), and the shift was
definitely perceptible.  I worked around it by adjusting the camera
angle, but there's got to be a better way.

I would venture to say that the centerpoint of the screen is always
rounded up or down, instead of being left at, say, (319.5,239.5),
which is where it should be for a 640x480 screen.
