-// ***** OculusWorldDemo Description
-
-// This app renders a simple flat-shaded room allowing the user to move along the
-// floor and look around with an HMD, mouse and keyboard. The following keys work:
-//
-// 'W', 'S', 'A', 'D' and Arrow Keys - Move forward, back; strafe left/right.
-// F1 - No stereo, no distortion.
-// F2 - Stereo, no distortion.
-// F3 - Stereo and distortion.
-// F4 - Toggle MSAA.
-// F9 - Cycle through fullscreen and windowed modes. Necessary for previewing content with Rift.
-//
-// Important Oculus-specific logic can be found at following locations:
-//
-// OculusWorldDemoApp::OnStartup - This function will initialize OVR::DeviceManager and HMD,
-// creating SensorDevice and attaching it to SensorFusion.
-// This needs to be done before obtaining sensor data.
-//
-// OculusWorldDemoApp::OnIdle - Here we poll SensorFusion for orientation, apply it
-// to the scene and handle movement.
-// Stereo rendering is also done here, by delegating to
-// to Render function for each eye.
-//
-
-//-------------------------------------------------------------------------------------
-// ***** OculusWorldDemo Application class
-
-// An instance of this class is created on application startup (main/WinMain).
-// It then works as follows:
-// - Graphics and HMD setup is done OculusWorldDemoApp::OnStartup(). This function
-// also creates the room model from Slab declarations.
-// - Per-frame processing is done in OnIdle(). This function processes
-// sensor and movement input and then renders the frame.
-// - Additional input processing is done in OnMouse, OnKey.
