// ***** OculusRoomTiny Description
// This app renders a simple flat-shaded room allowing the user to move along the
// floor and look around with an HMD, mouse, keyboard and gamepad.
// By default, the application will start full-screen on Oculus Rift.
//
// The following keys work:
//
// 'W', 'S', 'A', 'D' - Move forward, back; strafe left/right.
// F1 - No stereo, no distortion.
// F2 - Stereo, no distortion.
// F3 - Stereo and distortion.
//
// The world RHS coordinate system is defines as follows (as seen in perspective view):
// Y - Up
// Z - Back
// X - Right

// ***** OculusRoomTiny Application class
// An instance of this class is created on application startup (main/WinMain).
//
// It then works as follows:
//
// OnStartup - Window, graphics and HMD setup is done here.
// This function will initialize OVR::DeviceManager and HMD,
// creating SensorDevice and attaching it to SensorFusion.
// This needs to be done before obtaining sensor data.
//
// OnIdle - Does per-frame processing, processing SensorFusion and
// movement input and rendering the frame.
