no big difference for a 4000x2000 to cubefaces 1200 remapping tasks.
I stopped testing, since the old fixed kernel size interpolators and
the anti-alaising ones are not comparable. The kernel size (and hence
the execution time) highly depends on whether downsampling or
upsampling, and they increase for downsampling:
