Comment (by sdack):
So far the only response I got was to send in a feature request for Nvidia
to provide the new functions, which I've done.
CUDA 8.0 has been released and still provides no replacement functions.
They have even abandoned the use of some of the algorithms for this
function.
cubic2p_bspline, cubic2p_catmullrom and cubic2p_b05c03 now only produce an
error message (-22, Interpolation Error).
The npp_scale filter may need to be declared as deprecated.
