Mir latency chart

[Daniel van Vugt]

Will do. I think Sergio now has the requisite hardware for this.

And yes interval means swap interval. Swap interval 0 is included just 
out of interest. We don't intend to use zero in production because it 
wastes power at best, but also triggers driver problems on radeon and 
nouveau (https://bugs.launchpad.net/mir/+bug/1211700).
