Qml Preview: Record more detailed frame statistics
Just the number of frames per second doesn't tell us the reason for any
low frame rates. The problem could either be GPU-bound, and rendering
could take very long, or the problem could be CPU-bound, with
synchronizing or the gap between frames being very long.
Reporting the rendering and synchronization times in more detail gives
the client an idea of what is actually going on.
