Note: The current nohalo sampler is interpolatory. So are nearest neighbour, bilinear, and Lanczos. What this means is that if such samplers are combined with fast paths, AND the arithmetic is spotless, there would not be a "jump".
lohalo, which basically is an improved Mitchell-Netravali bicubic, is not interpolatory. (The only Keys cubic that is interpolatory is Catmull-Rom. Some people, e.g. Mathias Rauen of madVR fame, like non-Keys bicubics. But most people stick to Keys.)
