--- Comment #16 from Carlos Garcia Campos <cgarcia at igalia.com> ---
Many things have changed since the first time I tried to implement this for GTK port. Now we always use the threaded compositor for accelerated rendering, which means that frames are rendered in a secondary thread. That complicates things a bit, because we need to notify the inspector in the main thread. My initial patch  notified about frame start right before the contents were rendered into the GL context and the frame end after the swap buffers. But I'm not sure that's actually what we want here. I don't know how Core Animation works, so could someone explain when is begin/end frame and will/did composite expected to happen?
