VRHMDDemo([stereoscopic=1][, checkerboard=0][, withGazeTracking=0][, deviceindex=0])

A very basic demo for the most basic setup of VR HMDs, e.g., the Oculus
VR Rift DK2. It shows the absolute minimum of steps needed - one line of
code - to use the first connected HMD as mono or stereo display.

‘stereoscopic’ if set to 1 (which is the default), configures the
HMD as a stereoscopic display. A setting of 0 configures it as a
monoscopic display.

‘checkerboard’ if set to 1 draws a checkboard pattern instead of the
regular test image.

The optional parameter ‘withGazeTracking’, if provided and non-zero, will
enable some basic test of eye gaze tracking with VR HMD’s which support
eye tracking. Please note that this functionality is not available in
official Psychtoolbox releases yet, at least not as of v3.0.19.1, and the
api used in this demo is highly experimental and subject to backwards
incompatible changes!

‘deviceindex’ if provided, selects the HMD with given index. Otherwise
the first HMD (deviceindex 0) is chosen.

The demo just renders one static simple 2D image, or image pair in
stereoscopic mode, then displays it in a loop until a key is pressed.
