Summary Web Inspector: add experiment to show rendering information on inspector overlay

Reported 2012-09-26 04:57:30 PDT
Add a window that displays whether the object being inspected is a relayout boundary and whether it requires a layer. This may help web app developers to minimize time spent on layout by minimizing the invalidates relayout tree and minimize time spent on compositing by minimizing the number of layers.

Comment on attachment 166226 [details] Patch As we agreed offline, lets paint invalidate boundaries per layout in a "show paint rects" style.

Layer tree visualizations are in the web inspector, as are repaint rects. There is a separate bug somewhere for layout damage rects, which has been migrated to the new component.
