The hand state machine has the following features
* There's a idle to point animation, followed by a looping point hold state.
* There's a point to idle animation.
* The grab state is composed of a linear blend between an open and closed pose.
Additionally the C++ code will ramp on the left and right hand overlays,
This allows the fingers to be animated normally when the user is not actively
pointing or grabbing.
* Application: Forward trigger values to the MyAvatar's PalmData
* SkeletonModel: Pass PalmData to Rig via updateRigFromHandData() this is more explicit then
the Rig::inverseKinematics methods.
* AnimNodeLoader & AnimOverlay: add support for LeftHand and RightHand bone sets
* Rig::updateRigFromHandData() read the triggers and set stateMachine trigger vars
* avatar.json - udpated with new hand state machine with temporary animations
* In HMD mode head orientation and position is set.
* When not in HMD only orientation is set, position should
default to the underlying pose position.
Now triggers 7 states.
Idle, WalkFwd, WalkBwd, StrafeLeft, StrafeRight, TurnLeft & TurnRight.
As well as variable speed walking to match current velocity.
* Removed validation logic from Resource class, Qt does this internally and is more
standards compliant. This should result in more accurate caching and faster resource
fetching when cache is stale and validation fails.
* Added loaded and failed slots to Resource class, so it does not have to be polled.
* NetworkGeometry now uses multiple Resource objects to download
the fst/mapping file and the fbx/obj models.
* NetworkGeometry is no longer a subclass of Resource
* NetworkGeometry now has signals for success and failure, you no longer
have to poll it to determine when loading is complete (except for textures *sigh*)
Some functionality was removed
* NetworkGeometry no longer has a fallback
* NetworkGeometry no longer loads LODs or has lod logic.
* The number of FBXGeometry copies is greatly reduced.
* Model::setURL no supports fallback URL, delayLoad or retainCurrent option.
This can result in a pop when switching avatars, and there's no longer a default
if avatar loading fails.
