Fix T47210: Compostiting, Bad AA using distort + undistort nodes
Compositor tried to be too much smart and avoid unneeded re-calculations of
the distortion model, but the way it was implemented is by falling back to
the nearest interpolation first.
We can't really cheat here, better to just look into faster models estimation.
