- Revision ID: tarmac-20161111065942-evhm2zfdl8clzfmn
Enhance the ClientLatency acceptance tests to measure latency with
fractional precision.
This is required to test framedropping properly, which should always
achieve closer to zero than one whole frame of latency. In the new
Vulkan terminology, this is called Mailbox mode.
This is an important regression test not only for maintaining low
latency but also avoiding bugs like LP: #1379685 and LP: #1396006. Fixes: https://bugs.launchpad.net/bugs/1640366.
