-// ***** LatencyTest
-//
-// LatencyTest utility class wraps the low level LatencyTestDevice and manages the scheduling
-// of a latency test. A single test is composed of a series of individual latency measurements
-// which are used to derive min, max, and an average latency value.
-//
-// Developers are required to call the following methods:
-// SetDevice - Sets the LatencyTestDevice to be used for the tests.
-// ProcessInputs - This should be called at the same place in the code where the game engine
-// reads the headset orientation from LibOVR (typically done by calling
-// 'GetOrientation' on the SensorFusion object). Calling this at the right time
-// enables us to measure the same latency that occurs for headset orientation
-// changes.
-// DisplayScreenColor - The latency tester works by sensing the color of the pixels directly
-// beneath it. The color of these pixels can be set by drawing a small
-// quad at the end of the rendering stage. The quad should be small
-// such that it doesn't significantly impact the rendering of the scene,
-// but large enough to be 'seen' by the sensor. See the SDK
-// documentation for more information.
-// GetResultsString - Call this to get a string containing the most recent results.
-// If the string has already been gotten then NULL will be returned.
-// The string pointer will remain valid until the next time this
-// method is called.
-//

-// ***** LatencyTest2
-//
-// LatencyTest2 utility class wraps the low level SensorDevice and manages the scheduling
-// of a latency test. A single test is composed of a series of individual latency measurements
-// which are used to derive min, max, and an average latency value.
-//
-// Developers are required to call the following methods:
-// SetDevice - Sets the SensorDevice to be used for the tests.
-// ProcessInputs - This should be called at the same place in the code where the game engine
-// reads the headset orientation from LibOVR (typically done by calling
-// 'GetOrientation' on the SensorFusion object). Calling this at the right time
-// enables us to measure the same latency that occurs for headset orientation
-// changes.
-// DisplayScreenColor - The latency tester works by sensing the color of the pixels directly
-// beneath it. The color of these pixels can be set by drawing a small
-// quad at the end of the rendering stage. The quad should be small
-// such that it doesn't significantly impact the rendering of the scene,
-// but large enough to be 'seen' by the sensor. See the SDK
-// documentation for more information.
-// GetResultsString - Call this to get a string containing the most recent results.
-// If the string has already been gotten then NULL will be returned.
-// The string pointer will remain valid until the next time this
-// method is called.
-//
