I think it would be cool if Web Inspector supported paint flashing (like Quartz Debug).

Firefox 3.1 will have paint events that fire after a rect paints. http://ejohn.org/blog/browser-paint-events/ John Resig made a demo of paint flashing with these events. I think we can do better with just direct paint flashing.

I got this working on the Mac last night. Going to try and redo it at the WebCore level now.

I'd like to see the ability to have each RenderObject draw a repaint count in the corner. That makes it really obvious when things are redrawing too much.

WebKit2 has a mode that flashes backing store updates. Maybe we could use that. See WebPageProxy::setDebugPaintFlags
