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