// in VR-Vantage.  It creates a window with two channels.  It then creates a custom 
// channel-specific overlay for the second channel, and a second overlay that is
// drawn on all channels. It then shows how to put text objects onto the custom
// overlays, as well as text onto the default channel-specific for first channel.
