Hi Timo, As for the deprecation of libnpp, I suggest to keeping it. We use it a lot! In addition, we have some improvements for the current scale_npp... however, before publishing it it's necesssary to solve the question of the linking with libnpp. Regarding the static linking with libnpp, I

New version of the patch -- now it uses the same logic independent of the target bitdepth. For x86_64 it is much faster than current code (with perfect quality), for x86_32 it is fast if you add to configure: --extra-cflags="-msse2" (for x86_32 with default configure options it is slower than
