Deal with this FIXME.  Two layout tests fail if I just restore the old code:

  svg/filters/filter-on-svg-root-w-layer.html
  svg/custom/cross-referenced-resources.html

A full invalidation is still needed on the SVG root element if it has a filter. 
Adjust the code comment, and use the new code.  With that, the indicated layout
tests pass.

New patch uploaded: patch set #7.
