* Removed MyAvatar.reset() access from JavaScript
* Added HMD.centerUI() to JavaScript, which can be used to reset the 3D UI sphere around the current HMD orientation.
* Added MyAvatar.clearIKJOintLimitHistory() which can be used to reset any remembered IK joint limit history.
* Added MyAvatar.centerBody() which can be used to instantly re-orient the avatar's so that the hips and toes
are facing the same direction as the current HMD orientation.
away.js now uses the above new API's instead of MyAvatar.reset()
* When the overlay is hidden because your head is too close to the sphere,
instead of coming back immediately, it waits until the avatar's velocity is near zero
for a period of time.
* Hooked up jump and fly to MyAvatar::hasDriveInput()
* Added an internal state machine to OverlayConductor to manage hiding/showing transitions.
* The overlay menu state is now tied directly to the overlay, so it will change state as the
overlay is dynamically hidden/shown from code.
* Removed slot going directly from MenuOption::Overlays directly to OverlayConductor::setEnable().
Previously the HUD fading in/out would also recenter the hmd sensor and the avatar, which caused many problems including:
* The user's view could shift vertically.
* Your avatar would briefly go into t-pose
* other users would see your avatar go into t-pose.
Now we now move the UI sphere instead, which results in a much smoother experience.
MyAvatar: added hasDriveInput method.
OverlayConductor:
* removed avatar and sensor reset, instead the overlay's modelTransform is changed.
* revived STANDING mode, which is active if myAvatar->getClearOverlayWhenDriving() is true and you are wearing an HMD.
* SITTING & FLAT mode should be unchanged.
* Instead of using avatar velocity to fade out/fade in the hud, We use the presense or absanse of avatar drive input.
* Additionally, we check distance to the UI sphere, and quickly recenter the hud if the users head is too close to the actual hud sphere.
CompositorHelper:
* Bug fixes for ray picks not using the modelTransform.
HmdDisplayPlugin:
* Bug fixes for rendering not using the modelTransform.
Used to disable the 'room-scale' avatar re-centering code.
Disabling this can prevent sliding when the avatar is supposed to be sitting or mounted on a stationary object.
Also, removed a bunch of old, unused leaning and torso twisting code.
* Bug fix for eye tracking in HMD, the "up" orientation of your eyes now match your head.
* DebugDraw: added drawRay method.
* Application: Renamed preRender to postUpdate
* AvatarManager: added postUpdate method that iterates over all avatars.
* MyAvatar: Renamed preRender to preDisplaySide
* MyAvatar: split preRender code into postUpdate and preDisplaySide.
* Removed "Show who is looking at me", "Render focus indicator" and "Render lookat target" debug draw.
* Split "Show Look At Vectors" into "Show My Look At Vectors" and "Show Other Look At Vectors", to make it easier to debug eye tracking.
* "Show Look at Vectors" now draws the right eye red and the left eye blue.
* Removed Avatar and MyAvatar renderBody
* Removed look at rendering from head.
* GLMHelpers: Bugfix for generateBasisVectors when up primary and secondary axis were orthogonal
