Add _FilterArgs NamedTuple to ImageFilter

[radarhere]

See if you think this makes the code clearer.

I like the idea. Minor comments - things I had to look up to understand the flow, so maybe someone else would have to, too :)

I'd personally like to call this divisor, because that's what it practically is (and in fact, that's the "argument name" in _filter() in _imaging.c).

Kernel calls it scale.

Pillow/src/PIL/ImageFilter.py

Lines 72 to 78 in 5eee920

	def __init__(
	self,
	size: tuple[int, int],
	kernel: Sequence[float],
	scale: float | None = None,
	offset: float = 0,
	) -> None:

I would rather be consistent with the existing Python API.

Sure thing.

I'd kind of want to note that these are unpacked directly to ImagingCore.filter().

Ok, I've added a comment.
