I was looking for some documentation for the Lanczos resampling
filter, but I cannot find any mention of the default value for the
I see this in swscale.h:
For SWS_LANCZOS param tunes the width of the window function
I also see that SWS_PARAM_DEFAULT is 123456, whose purpose I don't
fully understand, but clearly it's not the right value. Or is it 6, as
shown in utils.c, line 412?
