The size of a filter can be as big as you wish. And it is neccessary to limit
the size of a buffer, especially if you have many filters. But as far as I
know, we don't have attributes or parameters to limit intermediate buffers with
context scaling for big filters.

Another point to add limitations here is filterRes. This code can be used to
add different resolutions for filters later.

I looked at SVGPerserveAspectRatio during some experiments with feImage. It
seems to be a bit to complex for this simple scaling of context and image with.
I haven't looked at Image yet.
