Working with the latency tester

The Oculus latency tester is a device that allows you to empirically test the time it takes between issuing the commands to render something on the Rift screen and the screen actually changing in response.  Someone on the Oculus forums recently asked why there weren't any test applications that you could download in order to use the device.  The reason for this is that such an application would defeat the purpose of the device, which is to allow you to measure the performance and latency of your program on your hardware.

Specifically it allows you to measure the amount of time you should be using in the sensor fusion prediction mechanism.
