Reviewed by Dirk Schulze.

When an attribute of a LightElement changes, it
send an update message to the lighting filters
to update its corresponding LightSource objects,
and repaint the filters.

Duplicated 'id' attributes removed from svg-filter-animation.svg.

Existing dynamic-update tests covers this feature.

5x speedup on manual-tests/svg-filter-animation.svg
