As someone who is implementing filter support in my renderer at the moment,
I can concur with this :)

It would be helpful if the spec gave some guidance on best practice for
determining an appropriate size for the filter bitmap.  By "filter bitmap"
I mean the intermediate bitmap used for SourceGraphic etc.  For axis
aligned content it is easy, but if the element has a transform, it is not
so straightforward.  In fact I notice that IE doesn't even try. It performs
all filters on the transformed content and doesn't use
