Defaults to the filter's preferred window if unset. Use
``scale-window=help`` to get a list of supported windowing functions.
``scale-wparam=<window>``
(Advanced users only) Configure the parameter for the window function
given by ``scale-window``. Ignored if the window is not tunable.
Currently, this affects the following window parameters:
kaiser
Window parameter (alpha). Defaults to 6.33.
blackman
Window parameter (alpha). Defaults to 0.16.
gaussian
Scale parameter (t). Increasing this makes the window wider.
Defaults to 1.
``scaler-resizes-only``
Disable the scaler if the video image is not resized. In that case,
``bilinear`` is used instead whatever is set with ``scale``. Bilinear
