I don't think having X only cubic interpolation will help much -
artifacts seen in bilinear interpolation are typically seen, because
horizontal/vertical interpolation is linear, while diagonal
interpolation is quadratic. If you interpolate cubic in X, this will not
change this basic property here. So I don't think it is worth the
hazzle.

I'll eventually try to update the code, and tell you how it performs on
i915 - which is about the least capable hardware ;)
