So mx/my/mw/mh should be dropped from the spec. Furthermore, we should get rid of the -10%/-10%/120%/120% hack and say that by default the filter region is infinite. Easier for authors, easier for implementors.


I agree in general, but like I wrote before, you still have filter primitives that can get infinite large. We still need some kind of region definition for them, or make the maximum size dependent of the union of all input filter primitives. Some examples that could get infinite large are lightning effects or feComposite with 'arithmentic'.
