This is a blend of the previous 'sitting' and 'standing' HMD modes.
Basically, when you move your head within a small range (20cm) your
avatar will lean appropriately, however when you cross that threshold
your body will move underneath you, re-centering your head above the body.
While this occurs the avatar should play the appropriate walking animations.
* vive rendering works again
* overlay fades away in standing mode, if you look or move away from the overlay sphere.
* middle mouse button can be used to fade in or out the overlay
* mouse pointer renders properly on overlay
Added OverlayConductor class that "orchestrates" Overlays, ApplicationCompositor & AppliationOverlay instances
so that the overlay can be smoothly animated on and off, mouse/key events are blocked when overlay is disabled.
