Boy, should really check here more often...
Just to quickly finish this discussion: Rays are sorted by *direction*, which is x/y. In this case, the ray was indeed going backwards (so what Newton said was right), but the mistake was in the Y coordinates. Reason for that was simply a rounding error, where a ray got reduced to about 1/1000 of a pixel, and in the process changed its orientation enough to point into a wrong direction. The fix is simply to eliminate such tiny rays instead of reducing them.
