filter_kernels: properly sharpen/blur filter radius
We currently always scaled the window to the size of the configured
radius. However, this is wrong - we should instead be scaling it to the
size of the sharpened/blurred kernel. Since the window is always
stretched to the configured size of the filter, we can accomplish this
easily by just multiplying the blur value into the filter radius
directly, and then using that adjusted radius in place of `f.radius`
everywhere.
On a side note, this gives a very minor performance boost to
ewa_lanczossharp for no downside.
