Elliptical Filtering artifact in small render

[Joelaff]

You can see the line where the mapping is trying to changing MIP levels (I assume).

I could not reproduce this with a larger render, even scaling the cube down to a similar size. This doesn't mean it won't happen, as I didn't try very hard.

Here is the scene, with the (8k) texturemap: http://meanmutha.com/EllipticalFailure.7z (~1.2MB)
