* No longer normalizing scale in AnimSkeleton and AnimClip
This means graph is animating in 'geometry' coordinates
before unit scale is even applied. This is necessary to
properly work with both Avatar based models and ModelEntity
based models
Many things are broken.
* debug rendering (translations are x100)
* IK hand targets
* follow cam
* I did not even dare to try HMD mode
* AnimSkeleton now returns AnimPoses by const ref.
* AnimDebugDraw: uses references to Poses on the stack instead of copies
within inner loops.
* AnimDebugDraw: Removed unnecessary universal refs in range based for loops.
* Now always works, regardless of whether or not Rig or AnimGraph animations
are enabled.
* Changed joint radius to 1 cm.
* Changed xyz axis length to 4 cm.
std::vector.reserve() and raw access do not mix.
raw access will only work if you push_back elements onto the vector
first. However this worked fine on MacOSX, probably due to differences
in STL implementations.
Some code clean up and some commented out debugging lines.
Debug rendering of animaions of fight club model is not working.
Not sure what frame these transformations are in.
* added AnimPose::copyFromNetworkAnim() which
should, re-map bone ids to match the current
skeleton, and fill in missing bones with bind
pose frames.
* added ability to set a skeleton on a node.
I might need to add a recursive version of this.
* it compiles!
* tests run!
