Description Matt Baker 2015-06-10 14:53:03 PDT
* SUMMARY
Rendering Frames timeline should distinguish between layout and painting.

In the Rendering Frames timeline, both layout and painting operations are listed in the “Layout” category. Layout and painting are two distinct operations in WebKit, and optimizations that reduce painting (e.g. compositing) often have no effect on layout, and vice versa.
