Interpolators could be kernels, too, when the window will be part of the filter operator. Then, separable interpolation could be much accelerated.

Any orthogonal affinity could be applied this way, i.e. if limited to translation and scaling. To be dispatched directly in warp().

It is also possible to make rotations semi-separable, using a sequence of shears, but not sure we would save time. As for the integral-factor resampling, this is a true convolution.
