<br>I need to have a good look at your proposed damage API. I'm pretty sure that we wouldn't be able to use it for complete SVG scenes, only one SVG primitive at a time, since the SVG pointer-events property and other issues (filters) require per-primitive adjustments to invalidation and hit testing ... so it may not be much win for us beyond the ability to get the extents of a path or glyph.<br>
