> Technically <use> supports invalidation when a target referenced element changes, no? I wonder if we could adapt some of that mechanism?
Well it clones the target into its shadow tree, so this is not really comparable.
Consider:
<filter id="foo">
<feImage xlink:href="#somerect"/>
</filter>
<rect id="someRect" fill="url(#gradient")/>
<linearGradient id="gradient"><stop/></linearGradient>
<image filter="url(#foo)"/>

Say I change the linearGradient stop offset using JS. That would invalidate the <linearGradient>, and cause a repaint of the "someRect". And that's where it stops. There's no connectionb etween "someRect" and the <feImage> that references it.

Note: I have already fixed this locally, by introducing a new HashMap<SVGElement*, OwnPtr<HashSet<SVGElement*>> > in SVGDocumentExtensions. SVGFEImageElement registers the hrefElement with itself there. I'll write up more details tomorrow, about to sleep :-)
