Most filter related classes don't implement svgAttributeChanged / childrenChanged.
Stuff like <rect filter="url(#myfilter)" onclick="document.getElementById('myfilter').setAttribute('filterUnits', 'objectBoundingBox')" />  doesn't work because of that -> the filter is not invalidated.
It's just a matter of adding invalidateResourceClient() calls in the right places, see SVGClipPathElement as example.

Tests need to be added to svg/dynamic-updates, covering changing filter attributes through DOM / SVG DOM.
